A highly efficient synthesis of phenanthridine/benzoxazine‐fused quinazolinones by ligand‐free palladium‐catalyzed intramolecular CHbondactivation under mild conditions has been developed. The CC coupling provides the corresponding N‐fused polycyclic heterocycles in good to excellent yields and with wide functional group tolerance.
