Comprehensive Summary

An efficient kinetic resolution (KR) protocol for 1,2-diamines has been developed through asymmetric electrophilic aminations of anilines enabled by chiral phosphoric acid catalysis. A wide array of substituted 1,2-diamines were compatible with this method, generating both the recovered staring materials and the amination products with high enantioselectivities (with s-factor up to 218). Notably, this method is amenable to the kinetic resolution of 1,2-diamines bearing α-tertiary amine moieties, which represents the first KR of this type of 1,2-diamines. Facile removal of the introduced hydrazine group and oxidative cleavage of the N-aryl group to release the free primary amine demonstrate the value of this method.image
