Phosphorus-substituted quaternary carbon stereocenters exist widely in drugs and biologically active compounds. Catalytic asymmetric synthesis of such quaternary carbon stereogenic centers is of significant importance, with four synthetic strategies being established. This review summarizes the recent progress in this field, including the advantages and limitations of each strategy, briefly discusses the reaction mechanisms and challenges, and outlines synthetic opportunities still open.1 Introduction2 Asymmetric Hydrophosphonylation3 Asymmetric Electrophilic Phosphination4 Asymmetric Functionalization of P-Substituted Methine Compounds5 Asymmetric Addition to α-Keto- or α-Ketiminophosphonates6 Conclusion

Vicinal Diamines

AbstractEnantioselective diamination of alkenes represents one of the most straightforward methods to access enantioenriched, vicinal diamines, which are not only frequently encountered in biologically active compounds, but also have broad applications in asymmetric synthesis. Although the analogous dihydroxylation of olefins is well-established, the development of enantioselective olefin diamination lags far behind. Nevertheless, several successful methods have been developed that operate by different reaction mechanisms, including a cycloaddition pathway, a two-electron redox pathway, and a radical pathway. This short review summarizes recent advances and identifies limitations, with the aim of inspiring further developments in this area.1 Introduction2 Cycloaddition Pathway3 Two-Electron Redox Pathway3.1 Pd(0)/Pd(II) Diamination3.2 Pd(II)/Pd(IV) Diamination3.3 I(I)/I(III) Diamination3.4 Se(II)/Se(IV) Diamination4 One-Electron Radical Pathway4.1 Cu-Catalyzed Diamination4.2 Fe-Catalyzed Diamination5 Summary and Outlook
