A diastereo- and enantioselective copper-catalyzed carboboronation of allene with aldimines and diborons under mild conditions is developed. This protocol is enabled by a chiral ANIPE-based copper catalyst, providing a facile and efficient approach to chiral homoallylic amines bearing two adjacent stereocenters with high enantioselectivities and diastereoselectivities. Besides, aldiminoester and ketiminoester could both serve as competent electrophiles for the production of enantioenriched α-amino esters.
