Recent Advances in the Catalytic Asymmetric Construction of Phosphorus-Substituted Quaternary Carbon Stereocenters

Abstract

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
