Photoinduced enantioselective strategies provide an efficient way to access chiral all-carbon quaternary stereocenters. Compared with the well-developed metal-catalyzed asymmetric conjugate addition of organometallic reagents to enones, the construction of chiral all-carbon quaternary stereocenters through a radical process still remains challenging, especially for the acyclic enones due to their enhanced conformational mobility. Herein, we disclose a photoinduced cobalt-catalyzed asymmetric radical coupling of alpha,beta-unsaturated 2-acyl imidazoles and alpha-silylamines to give beta,beta-di...
