Substituted phenanthridinones can be obtained with high regioselectivity and in very good yields by palladium‐catalyzed cyclization reactions of N‐methoxybenzamides with arenes (see scheme). The reaction proceeds through multiple oxidative CH activation and CC/CN formation steps in one pot at room temperature, and thus provides a simple method for generating bioactive phenanthridinones.
