One‐Pot Formation of CC and CN Bonds through Palladium‐Catalyzed Dual CH Activation: Synthesis of Phenanthridinones

Two cycles in one pot! The synthesis of biologically important phenanthridinones has been achieved by the one-pot formation of CC and CN bonds through a palladium-catalyzed dual CH activation, which involves four bond ruptures and two bond formations (see scheme). The conversion of phenanthridinones into natural product like derivatives further demonstrates the utility of this synthetic achievement.
