Organocatalytic Enantioselective Synthesis of P‐Stereogenic Chiral Oxazaphospholidines

Abstract

AbstractThe enantioselective synthesis of P‐stereogenic chiral organophosphines under organocatalysis is a challenging research field, and reports that use this approach are rare. Herein, we have developed the enantioselective synthesis of P‐stereogenic chiral oxazaphospholidines by using a bicyclic thiazole as the organocatalyst in the P–N and P–O bond‐forming reaction. The P‐chiral products were prepared in high yields with moderate enantioselectivities. The base that was used in this process had a significant influence on the enantioselectivity of the reaction and in some cases led to the opposite configuration of the P‐chiral center.
