Direct Access to Isoindolin‐1‐one Scaffolds by Copper‐Catalyzed Divergent Cyclizations of 2‐Formylbenzonitrile and Diaryliodonium Salts

Abstract

Abstract Copper‐catalyzed cascade transformations of 2‐formylbenzonitrile and diaryliodonium salts were carried out to efficiently afford isoindolin‐1‐one scaffolds. The process proceeds through a copper‐catalyzed tandem C–H/N–H arylation, producing two different isoindolin‐1‐one derivatives under different reaction conditions. magnified image
