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.).
Selective Synthesis of 3-Arylbenzo-1,2,3-triazin-4(3H)-ones and 1-Aryl-(1H)-benzo-1,2,3-triazoles from 1,3-Diaryltriazenes through Pd(0) Catalyzed Annulation Reactions
