Palladium‐Catalyzed Oxidative CC Bond Cleavage Cyclization of Biaryl‐2‐amines with Alkenes Involving CH Olefination and Carboamination

A new, general method for the synthesis of phenanthridines has been developed by palladium-catalyzed oxidative remote CH olefination–carboamination–CC bond cleavage tandem reaction. It is noteworthy that alkenes are used as the one-carbon resources for this tandem reaction.
