Enantioselective radical conjugate additions driven by a photoactive intramolecular iminium-ion-based EDA complex

Abstract

In enantioselective catalysis, electron donor–acceptor (EDA) complexes are usually photochemically activated in an intermolecular fashion. Here, the authors report the stereoselective conjugate addition to β-substituted cyclic enones proceeding without external photoredox catalysts via an intramolecular EDA complex.
