Graphical Abstract

One, two, three! A three-component radical cascade for the enantioselective synthesis of γ-amino-acid derivatives is presented. The reactions proceed by redox and phosphoric acid dual catalysis, and work with readily available starting materials.

Abstract

An enantioselective three-component radical reaction of quinolines or pyridines with enamides and α-bromo carbonyl compounds by dual photoredox and chiral Brønsted acid catalysis is presented. A range of valuable chiral γ-amino-acid derivatives are accessible in high chemo-, regio-, and enantioselectivity from simple, readily available starting materials under mild reaction conditions. Using the same strategy, the asymmetric synthesis of 1,2-diamine derivatives is also reported.
