Progress in the Application of Ming-Phos Ligands in Transition-Metal-Catalyzed Reactions Xu Bing1, Zhang Zhan-ming*2, Zhang Jun-liang*2 (1. School of Pharmacy, Naval Medical University, Shanghai 200433, China; 2.Department of Chemistry, Fudan University, Shanghai 200438, China) 

AbstractChiral ligands are the core factor for achieving high enantioselectivity in transition-metal-catalyzed asymmetric reactions. Among them, chiral phosphine ligands, as the earliest studied and most widely applied category of chiral ligands, have always attracted significant attention from chemical researchers. In 2014, the research group of Junliang Zhang successfully developed the first Sadphos ligand, namely Ming-Phos, based on the design concepts of non-C? symmetry, a balance between rigidity and flexibility, and the integration of both hard and soft coordinating atoms (O, S, N, and P atoms). Ming-Phos has received extensive attention due to its prominent advantages such as rich structural diversity, ease of modification, and scalability in preparation. To date, Ming-Phos ligands have been employed in asymmetric reactions catalyzed by six metals (gold, silver, copper, palladium, rhodium, and nickel), encompassing diverse reaction types including [3+2] cycloaddition, [4+3] cycloaddition, intramolecular Heck reaction, Heck/Sonogashira reaction, Narasaka-Heck/silylation reaction, Narasaka-Heck/Sonogashira reaction, Larock indole synthesis, Suzuki coupling, Sonogashira coupling, ring expansion, reductive cyclization/cross-coupling, and three-component reaction. Furthermore, Ming-Phos ligands have exhibited superior regioselectivity and reactivity in the polymerization of allene monomers. Over a decade of development, Ming-Phos ligands have fully demonstrated significant potential in the fields of asymmetric catalysis and materials science. This paper systematically reviewed the application progress of Ming-Phos ligands in asymmetric reactions catalyzed by transition metals (including gold, silver, copper, palladium, rhodium, and nickel) as well as in polymerization reactions, and provides an outlook on its future development directions.

摘要:自由基反應在合成化學領域應用非常廣泛,但是自由基高活性的特征使得反應的立體選擇性控制充滿挑戰。圍繞不對稱催化自由基反應這一領域,提出/手性多齒陰離子配體策略,核心在于設計手性多齒陰離子配體,其不僅能顯著增強銅催化劑的還原性,解決自由基反應啟動的難題,還能夠通過調控銅催化劑的手性環境實現高活性自由基物種的立體選擇性調控。基于該設計思路,首先開發了銅/N,N,P(N)配體催化劑,發展了烷基鹵代烴交叉偶聯、烯烴雙官能化、烷烴碳氫官能化等不對稱催化自由基反應,實現了多種手性化學鍵,如碳-碳、碳-雜、雜-雜鍵的高效構筑。針對純烷基自由基這類挑戰性底物,進一步開發了新型空間限域型配體,通過獨特的手性口袋設計突破立體識別瓶頸,實現了該類自由基的立體選擇性控制,高效構筑手性碳-氮鍵;此外,還設計了Hemilabile型及長邊臂型N,N,N配體,解決了烯基硼酸酯偶聯、大位阻底物反應中的立體選擇性問題。此外,該策略也得到了國內外眾多課題組的驗證。上述/手性多齒陰離子配體策略的提出與應用,推動了不對稱自由基化學的發展。

Copper/Multidentate Anionic Ligand-Catalyzed Asymmetric Radical Reactions CHEN Zheng1, DONG Xiao-yang2, LI Zhong-liang*2, LIU Xin-yuan*1 (1.Department of Chemistry, Southern University of Science and Technology, Shenzhen 518055, China; 2.School of Physical Sciences, Great Bay University, Dongguan 523000, China)

Abstract: Radical reactions have found broad applications in organic synthesis. However, their high reactivity presents formidable challenges for enantiocontrol. Our team has developed "copper/chiral multidentate anionic ligand" to achieve asymmetric radical transformations. The ligand performs a dual role: it can not only enhance copper's reducing capacity to initiate the radical process but also provide good chrial environment for enantiocontrol over highly reactive radical intermediates. This approach facilitated the development of copper/N,N,P(N)-ligand catalysts, enabling asymmetric transformations, such as enantioconvergent cross-coupling of racemic alkyl halides, alkene difunctionalizations, and C-H functionalizations for efficient construction of chiral C-C, C-heteroatom, and heteroatom?heteroatom bonds. To achieve the enantiocontrol over purely alkyl radicals, we developed spatially confined chiral catalysts. These catalysts feature a chiral pocket characterized by a sterically constrained region around the catalytic center and an expanded spatial cavity at the periphery. Thus, it allows the construction of chiral C-N bond. In addition, we developed hemilabile and long-arm N,N,N-ligands to solve the issues associated with alkenylboronate and sterically encumbered substrates. This strategy has been validated by numerous research groups and provides significantly advances for asymmetric radical chemistry.

Synthesis of A New Manganese Complex and its Application in Catalytic Hydrogenation of Quinolines YANG Hao-bo, LIU Qiang* (Department of Chemistry, Tsinghua University, Beijing 100084, China)

Abstract: 1,2,3,4-Tetrahydroquinoline and its derivatives are important organic compounds, which are widely present in the frameworks of pharmaceuticals and bioactive molecules. Catalytic hydrogenation of quinolines using hydrogen gas as hydrogen source is the most direct, most effective, and most atom-ecomomical method to obtain tetrahydroquinoline. Furthermore, quinoline is also a promising liquid organic hydrogen storage material. Hydrogen gas can be converted into liquid tetrahydroquinoline through catalytic hydrogenation, which is easy to store and transport. In order to realizing the hydrogenation of quinoline under milder conditions, we designed and synthesised a novel NNP pincer manganese complex [Mn(CO)3{N-((1H-imidazol-2-yl)methyl-3- (diphenylphosphaneyl)propan-1-amine}]Br with high catalytic activity based on our previous work. The structure of that manganese complex was characterized in detail by 1HNMR, 13CNMR, 31PNMR, IR, HRMS and XRD. What’s more, quinoline could be hydrogenated into tetrahydroquinoline almost quantitatively at room temperature catalyzed by 2 mol% that novel NNP pincer manganese complexes with 20 mol% tBuONa as catalyst-activation reagent, tetrahydrofuran as solvent, and 3MPa hydrogen gas as hydrogen source. The quinoline substrates were studied, and eleven target products were obtained with yields of at least 80%. These results showed high activity and broad substrate scope of this catalytic system.

Abstract: In recent decades, significant advancements have been achieved in the field of transition metal-catalyzed asymmetric reactions. Among these, asymmetric carbonyl addition reactions have attracted considerable attention due to their efficiency in constructing carbon?carbon bonds and directly producing chiral alcohol compounds. Chiral alcohols are prevalent in drugs and natural products, rendering these reactions highly valuable in organic synthesis. Chiral N-heterocyclic carbene (NHC) ligands, characterized by their distinctive electronic properties and spatial configurations, have shown immense potential in asymmetric catalysis. This article provided a comprehensive review of recent developments in NHC/metal-catalyzed asymmetric carbonyl addition reactions, encompassing the asymmetric arylation, alkenylation, and alkylation of substrates such as ketones, aldehydes, and imines, as well as the exploration of dynamic kinetic asymmetric transformation strategies. The substrate scope, synthetic applications and reaction mechanisms of various transformations were systematically discussed. By integrating mechanistic experiments with density functional theory (DFT) calculations, it explored the η2-coordination activation mode of carbonyl compounds, highlighting the pivotal role of chiral NHC ligands in enhancing reaction efficiency and achieving enantioselective control. In conclusion, the article outlined the current challenges in the field, including reactivity disparities among different substrate classes and limitations in enantioselective and diastereoselective regulation, while also offering perspectives on future research directions. This aims to provide insights for the design of novel chiral NHC ligands and their broader applications in asymmetric catalysis.

摘要:手性聯咪唑啉(BiIM)配體與手性雙?f唑啉(BOX)體系中的聯?f唑啉(BiOX)存在顯著的結構同源性,其特征在于以氮原子替代氧原子構筑核心骨架。這一結構特征賦予BiIM配體獨特的化學屬性:通過在特定位置引入多樣化取代基,可實現對配位性能的精準電子效應調控,有效調節空間位阻參數與分子剛性,并為非均相催化體系的創新設計提供結構基礎。自2001Dupont研究團隊首次完成BiIM配體的合成,Casey、宋毛平團隊持續優化合成方法,陸展課題組創新性地以天然α-氨基酸為起始原料,采用模塊化合成策略,成功構建了結構豐富的N-烷基及N-芳基聯咪唑啉配體庫。在不對稱催化領域,陸展團隊率先將BiIM配體應用于不對稱自由基交叉偶聯反應體系,實現了芐位C-H鍵的高效芳基化、烯基化。此后,BilM在自由基反應領域得到了廣泛的關注,無論是在二組分反應還是在三組分反應中都可以適用。盡管當前BiIM配體在實際應用中仍存在體系局限性,且自由基反應固有的選擇性控制等問題亟待解決,但通過配體結構的理性設計優化,并結合計算化學模擬與高通量篩選技術,有望進一步拓展其在藥物合成、復雜分子構建等前沿領域的應用潛力,為現代有機合成化學提供高效的催化策略與技術手段。

Synthesis and Application of Chiral Biimidazolines in Asymmetric Radical Couplings ZHONG Cheng-cheng, LU Zhan* (State Key Laboratory of Soil Pollution Control and safety, Department of Chemistry, Zhejiang University, Hangzhou 310058, China)

AbstractThe chiral bipyrimidinol (BiIM) ligand and the chiral bisoxazoline (BOX) system exhibit significant structural homology, characterized by the substitution of nitrogen atoms for oxygen atoms to construct the core framework. This structural feature endows the BiIM ligand with unique chemical properties: by introducing diverse substituents at specific positions, precise electronic effects on coordination performance can be achieved, effectively regulating steric parameters and molecular rigidity, and providing a structural foundation for innovative design in heterogeneous catalytic systems. Since the first synthesis of the BiIM ligand by the Dupont research team in 2001, the Casey and Song Maoping teams have continuously optimized the synthetic methods. The Lu Zhan group innovatively used natural α-amino acids as starting materials and adopted a modular synthesis strategy to successfully construct a structurally rich library of N-alkyl and N-aryl bipyrimidinol ligands. In asymmetric catalysis, the Lu Zhan team was the first to apply the BiIM ligand to asymmetric radical cross-coupling reaction systems, achieving efficient arylation and alkenylation of benzylic C-H bonds. Subsequently, BilM has received extensive attention in radical reactions, applicable in both two-component and three-component reactions. Despite current limitations in practical applications of BiIM ligands and inherent selectivity control issues in radical reactions, rational design optimization of ligand structures combined with computational chemistry simulations and high-throughput screening techniques may further expand their application potential in drug synthesis and complex molecule construction, providing efficient catalytic strategies and technological means for modern organic synthesis chemistry.

摘要:不對稱氫化是制備手性化合物的重要手段,具有高原子經濟性,高效高選擇性及環境友好等優點。反應使用的催化劑通常由過渡金屬和手性三價膦配體組成。由于三價膦單元對空氣和水極度敏感,增加了不對稱氫化的操作難度。二級膦氧SPO是一類結構獨特的含磷化合物,其分子結構存在五價磷形態的膦氧和三價磷形態的亞膦酸的互變異構,在自由狀態下以對空氣和水穩定的膦氧結構存在,而與過渡金屬配位時則通常使用配位能力更強的三價磷形態。手性二級膦氧化合物的手性中心可位于磷原子上、磷的取代基上,或者二者兼具手性,具有廣泛的結構可調性。二級膦氧與金屬配位后產生的磷-羥基官能團可作為氫鍵的供體協助活化底物。手性二級膦氧的這些特性使其成為一類極具潛力的配體類型。近年來,多類結構多樣的手性二級膦氧被設計合成出來,并應用于過渡金屬催化的碳碳雙鍵、碳氧雙鍵和碳氮雙鍵的不對稱氫化中,取得了優異的催化活性和對映選擇性,部分催化體系已在生物活性分子的高效不對稱合成中發揮作用。根據手性二級膦氧配體的結構進行分類,系統地總結了其作為配體在多種不飽和底物的不對稱氫化中的應用進展和存在的局限,并對后續的發展進行了展望。

Research Progress of Chiral Secondary Phosphine Oxides in Asymmetric Hydrogenation Reactions ZHAO Meng-long, HAN Zhao-bin*( State Key Laboratory of Organometallic Chemistry, Shanghai Institute of Organic Chemistry, Chinese Academy of Sciences, Shanghai 200032, China) 

AbstractAsymmetric hydrogenation is an important method for the preparation of chiral compounds, featuring advantages such as high atom economy, high efficiency, high selectivity, and environmental friendliness. The catalysts used are typically composed of transition metals and chiral trivalent phosphine ligands. However, trivalent phosphine moieties are normally sensitive to air and moisture, which increases the operational difficulty of asymmetric hydrogenation. Secondary phosphine oxides (SPOs), a unique class of phosphorus-containing compounds, exhibit a tautomeric equilibrium between the phosphine oxide (pentavalent phosphorus form) and the phosphinous acid (trivalent phosphorus form). SPOs normally exist in the phosphine oxide form in the free state, which is inert to air and moisture. While in coordination with transition metals, they preferentially adopt the trivalent phosphorus form with stronger coordination ability. The chiral elements of chiral secondary phosphine oxides can be located on the phosphorus atom, in the substituents of phosphorus, or both, offering extensive structural tunability. The phosphorus-hydroxyl (P-OH) functional group generated after the coordination of secondary phosphine oxide with transition metal can act as hydrogen bond donors to assist in in substrate activation. These characteristics make chiral secondary phosphine oxides a highly promising class of ligands. In recent years, numerous structurally diverse chiral SPOs have been designed, synthesized, and successfully applied in transition metal catalyzed asymmetric hydrogenation of unsaturated double bonds including C=C bonds, C=O bonds, and C=N bonds. These catalysts have demonstrated excellent activity and enantioselectivity, wherein several catalytic systems have proven effective in the efficient synthesis of bioactive molecules. Based on the structural classification of chiral secondary phosphine oxide ligands, the advances and challenges in using SPOs as chiral ligands in transition metalcatalyzed asymmetric hydrogenation of diverse unsaturated substrates were summarized,  and the prospects of future developments in this field are also discussed.

摘要:手性膦配體在不對稱催化反應中發揮著核心作用,其膦原子上的取代基類型對反應活性、化學選擇性及立體選擇性具有關鍵影響。富電子二環己基取代的膦結構因優異性能,已在多種手性配體中得到成功應用并展現出高效催化活性。基于此,張俊良課題組將大位阻富電子二環己基膦基團引入自主研發的Sadphos配體骨架,設計合成了一系列含二環己基單膦結構的手性配體Xu-Phos。該類配體具有結構簡潔、易于修飾的特點,且兼具不同軟硬程度的配位原子,可與過渡金屬形成靈活的配位模式,是一類極具應用潛力的手性配體。綜述了近年來以Xu-Phos為優勢手性配體開發的過渡金屬催化不對稱轉化反應研究進展。自2018年首次報道以來,鈀與Xu-Phos形成的催化體系穩定性優異,已成功驅動一系列Heck反應及其相關串聯反應:通過烯烴、炔烴的對映選擇性Heck反應,可高效構建螺手性、中心手性及軸手性化合物;對于芳基碘化物連接的烯烴底物,其對映選擇性Heck反應可通過還原、碳鹵鍵還原消除、Suzuki偶聯、Sonogashira 偶聯、親核鈀化、硼化及遠程碳-氫烷基化等多種路徑終止,從而高化學選擇性、高立體選擇性地合成結構多樣的苯并雜環衍生物。此外,Xu-Phos在鈀催化的烯烴碳胺化、碳醚化、分子內碳氫鍵活化及消除反應中亦表現出優異的不對稱誘導能力,可精準構建多取代雜環化合物及軸向手性環己叉基骨架。除鈀催化體系外,Xu-Phos在其他金屬催化的不對稱反應中也展現出良好應用前景:在銅催化不對稱加成反應中可高效合成手性芳基亞磺酰胺;作為手性單齒膦配體應用于銥催化體系時,能實現酮與仲胺的直接不對稱還原胺化反應。

Progress in the Application of Xu-Phos Ligands in Transition-Metal-Catalyzed Asymmetric Reactions Xu Bing1, Zhang Zhan-ming*2, Zhang Jun-liang*2 (1. School of Pharmacy, Naval Medical University, Shanghai 200433, China; 2.Department of Chemistry, Fudan University, Shanghai 200438, China) 

AbstractChiral phosphine ligands play a central role in asymmetric catalytic reactions, and the types of substituents on their phosphorus atoms have a critical impact on reaction activity, chemo- and stereoselectivity. Phosphine structures with electron-rich dicyclohexyl substituents have been successfully applied in various chiral ligands and demonstrated high catalytic activity due to their excellent performance. Based on this, the research group of Junliang Zhang introduced the sterically hindered and electron-rich dicyclohexylphosphine group into the self-developed Sadphos ligand framework, designing and synthesizing a series of chiral ligands named Xu-Phos that contain a dicyclohexyl monophosphine structure. These ligands feature a simple structure, easy modification, and possess coordination atoms with different hardness and softness, enabling flexible coordination with transition metals, thus emerging as a class of chiral ligands with great application potential. This paper reviewed the research progress in the development of transition-metal-catalyzed asymmetric transformation reactions using Xu-Phos as a privileged chiral ligand in recent years. Since its first report in 2018, the catalytic system formed by palladium and Xu-Phos has exhibited excellent stability and successfully driven a series of Heck reactions and their related tandem reactions: Enantioselective Heck reactions of alkenes and alkynes allow for the efficient construction of spirochiral, central chiral, and axially chiral compounds; For alkene substrates linked to aryl iodides, their enantioselective Heck reactions can be terminated through multiple pathways such as reduction, reductive elimination of carbon-halogen bonds, Suzuki coupling, Sonogashira coupling, nucleophilic palladation, borylation, and remote C-H alkylation, thereby generating structurally diverse benzheterocyclic derivatives with high chemo- and stereoselectivity. In addition, Xu-Phos also shows excellent asymmetric induction ability in palladium-catalyzed alkene carboamination, carboetherification, intramolecular C-H bond activation, and elimination reactions, enabling the precise construction of various substituted heterocyclic compounds and axially chiral cyclohexylidene skeletons. Beyond its outstanding performance in palladium-catalyzed asymmetric reactions, Xu-Phos has also shown promise in other metal-catalyzed reactions. It can efficiently synthesize chiral aryl sulfinamides through copper-catalyzed asymmetric addition reactions. When applied as a chiral monodentate phosphine ligand in iridium-catalyzed systems, Xu-Phos enables the direct asymmetric reductive amination of ketones with secondary amines.

AbstractThis paper reported the synthetic process of tris(2-N,N-dimethylaminobenzyl) rare earth complexes (RER?, RE = Y, La, Sm; R =-o-CH?C?H?NMe?). The efficient preparation of the target complexes was achieved through the metathesis reactions between rare earth halides (REX?) and 2-N,N-dimethylamino benzyl lithium/potassium salts. The products were characterized by elemental analysis (EA), 1H NMR spectroscopy, ICP-MS. This study systematically explored the influence of key parameters, such as reaction time, temperature, feed ratio, recrystallization conditions, on the product yield and purity. The optimal conditions were as follows: the feed ratio controlled at n(M-o-CH?C?H?NMe?):n(RECl?) = 2.95:1 (M=Li/K), reaction temperature at 25 ℃ in THF for 2 hours, and recrystallization in the mixture of toluene and n-hexane. The target products were obtained in >90% yields and >99% purity for rare earth. Through refined process control, this study has significantly improved the synthesis efficiency and purity of rare earth benzyl complexes. The established reaction route features both operational convenience and industrial scalability, while providing a reference technical route and experimental basis for the development of synthesis processes for other rare earth complexes. It is expected to further promote the in-depth research, development and practical application of rare earth complexes in fields such as high-end catalysis and new energy materials, and offer technical support for the high-value utilization of rare earth resources.

摘要:α-炔基重氮酮作為一種重要的有機合成中間體,由于其既可以用作卡賓前體實現卡賓的反應,又可以發生Wolff重排生成含有炔基的乙烯酮中間體參與后續轉化,近年來正逐漸受到關注。然而,現有的合成方法具有一定的局限性:僅限于使用預先制備的α-炔基酮并通過重氮轉移反應得到對應的α-炔基重氮酮。該方法具有以下缺點:1)綜合產率較低;2)步驟繁瑣需要多次溫度調控3)反應原料α-炔基酮穩定性差,難以長期保存。因此,開發一種高效便捷的合成方法是必要的。基于此,設計了以α-芳基重氮Weinreb酰胺為關鍵前體的α-炔基重氮酮的合成策略。該策略具有官能團耐受性良好,反應條件溫和,步驟簡便,產率中等至優異等優點。同時,該策略也兼容炔丙基衍生物,為天然產物的衍生提供了平臺。

Efficient Synthesis of α-Alkynyl Diazo Ketones  XU Tian-yuan, NI Yu-hao, LIU Lu* (School of Chemistry and Molecular Engineering, East China Normal University, Shanghai 200241, China) 

Abstractα-Alkynyl diazo ketones, as important intermediates in organic synthesis, have garnered increasing attention in recent years due to their dual reactivity: they can serve as carbene precursors to undergo carbene-involved reactions or undergo Wolff rearrangement to generate alkynyl-containing ketene intermediates for subsequent transformations. However, existing synthetic methods exhibit certain limitations, being restricted to the use of pre-prepared α-alkynyl ketones followed by diazo transfer reactions to yield the corresponding α-alkynyl diazo ketones. This approach suffers from several drawbacks: 1) low overall yields; 2) tedious procedures requiring multiple temperature adjustments; 3) poor stability of the starting α-alkynyl ketones, which are difficult to store long-term. Therefore, the development of an efficient and convenient synthetic method is imperative. To address this, a novel strategy for synthesizing α-alkynyl diazo ketones has been designed, employing α-aryl diazo Weinreb amides as key precursors. This strategy offers several advantages, including excellent functional group tolerance, mild reaction conditions, straightforward procedures, and moderate to excellent yields. Additionally, this approach is compatible with propargyl derivatives, providing a versatile platform for the derivatization of natural products.

AbstractN-heterocyclic carbenes (NHCs), known for their strong σ-donating properties and tunable stereo-electronic effects, have found extensive applications in organic catalysis, transition metal catalysis, photocatalytic synthesis, and the preparation of functional materials. Among them, Pd-IPrBIDEA, an imidazolium-type NHC-palladium complex featuring a novel dibenzobarrelene moiety, distinguishes itself. Unlike conventional NHC complexes, IPrBIDEA- Pd incorporates butterfly-wing-like aromatic rings into its imidazolium core, playing a pivotal role in catalytic processes. This innovative design effectively restricts the flipping of aromatic amines around the C?N bond, thereby suppressing β?H elimination and catalyst deactivation. As a result, it significantly enhances the catalyst's turnover frequency, activity, and the selectivity of reactions. This review provided a comprehensive introduction to the design, synthesis, and characterization of IPrBIDEA- Pd complex, accompanied by a detailed discussion of its application in organic synthesis, including the ring-opening reduction and coupling reaction of gem-difluorocyclopropanes, the cross-coupling reaction of 2-fluoroallyl carbonates with allyl boronates, the Suzuki-Miyaura reaction involving heteroaryl chlorides, and the Suzuki-Miyaura polycondensation involving heteroaryl dichlorides. Consequently, it is anticipated that the potential applications of IPrBIDEA ligand and its derivatives and metal complexes in the domains of synthetic chemistry, catalytic science, and the development of new functional materials can be further advanced.

PC-Phos: A Xanthene-Derived Chiral Sulfinamide-Phosphine Ligand Zhang Pei-Chao*1, Zhang Wen-wen1, Zhao Qing-jie1, Zhang Jun-liang*2(1.School of Pharmacy, Naval Medical University, Shanghai 200433, China; 2.Department of Chemistry, Fudan University, Shanghai 200438, China) 

AbstractAsymmetric catalysis is the most efficient approach for the synthesis of chiral functional molecules, among which the chiral transfer of ligands is the key to achieving asymmetric catalysis. The design and development of "IDEAL" ligands have always been the common goal pursued by synthetic chemists and the industry. In the past decade, based on the design concept of "ideal ligands", a new generation of dynamically adaptive chiral sulfinamide phosphine ligands of the Sadphos family with diverse electrical properties, skeletons and side arms have been continuously developed and applied. Currently, electronic tuning strategies―modulating the phosphorus atom’s electronegativity and the steric hindrance of the ligands―have led to the successive development of Xiang-Phos, Xu-Phos, and TY-Phos. Skeletal tuning, involving adjustment of coordination group bond angles and backbone rigidity, has afforded Xiao-Phos, PC-Phos, WJ-Phos, Le-Phos, and GF-Phos. Moreover, side-arm assembly through incorporation of diphenylmethylphosphine has enabled the design of a class of chiral tert-butanesulfinamide-based bisphosphine ligands, as well as the multifunctional organophosphorus catalyst Wei-Phos. As one of the most successful chiral ligands based on a xanthene scaffold, PC-Phos has demonstrated excellent catalytic activity, chemoselectivity, and stereoselectivity control in various asymmetric transformations, including Pictet?Spengler cyclization, C?S/C?P coupling, Suzuki coupling, kinetic resolution via dearomatization, palladium-heteroallyl cycloaddition, and tandem Heck/Tsuji?Trost reactions. This review focuses on the design and application of PC-Phos, a new type of Sadphos with the xanthene skeleton, and systematically summarizes its research progress in transition metal-catalyzed asymmetric reactions from 2017 to 2025.

Key wordsphosphine ligands; chiral sulfinamide; asymmetric catalysis;xanthene; Sadphos
