Organocatalytic Enantioselective Synthesis of P ‐Stereogenic Chiral Oxazaphospholidines

The 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.
