An easy synthetic approach to 1,2,3-triazole-fused heterocycles

A convenient synthesis of 1,2,3-triazole-fused isoindolines and dihydroisoquinolines in good to excellent yield is reported, starting from easily available terminal alkynes and (2-haloaryl)alkylazides. The method is based upon a cycloaddition reaction, via click chemistry, followed by a transition metal-catalyzed functionalization of a C–H bond.
