Allylic C(sp3)-H alkylationviasynergistic organo- And photoredox catalyzed radical addition to imines

Abstract

A new catalytic method for the direct alkylation of allylic C(sp3)-H bonds from unactivated alkenesviasynergistic organo- and photoredox catalysis is described. The transformation achieves an efficient, redox-neutral synthesis of homoallylamines with broad functional group tolerance, under very mild reaction conditions. Mechanistic investigations indicate that the reaction proceeds through theN-centered radical intermediate which is generated by the allylic radical addition to the imine.
