Enantioselective direct-addition of terminal alkynes to imines catalyzed by copper(I)pybox complex in water and in toluene.

Chunmei Wei1, Chao-Jun Li.   

Abstract

Highly enantioselective direct alkyne-imine additions catalyzed by Cu(I)OTf and Evan's pybox ligands were developed in water and in toluene. The process is simple and provides a diverse range of propargylic amine in high ee and good yield.
