Catalyticenantioselective chemical reactions involving highly reactive radical species remain largely unexplored. We report herein for the first time a novel enantioselective radical ring-opening cyanation of redox-active oxime esters by dual photoreodox and copper catalysis. This mild protocol shows good functional group tolerance and broad substrate scope, producing a wide range of optically active
Direct arylation of cyclopentanones has been a long‐standing challenge because of competitive self‐aldol condensation and multiple arylations. Reported herein is a direct mono‐α‐C−H arylation of cyclopentanones with aryl bromides which is enabled by palladium/amine cooperative catalysis. This method is scalable and chemoselective with broad functional‐group tolerance. Application to controlled sequential
