The synthesis of phenanthridinones via denitrogenative annulation of 1,2,3-benzotriazin-4-(3H)-ones with arynes catalysed by Ni(0)/dppm was successfully developed. A variety of phenanthridinones were prepared in good to excellent yields. Based on this method, nature product, N-methylcrinasidine, was synthesized. (Figure presented.).
