An efficient one-pot synthesis of 1,2,3-triazole-fused isoindoles from o-alkynylbenzaldehydes and trimethylsilyl azide (TMSN3) is reported. The reaction proceeds through the formation of a diazide intermediate and a subsequent intramolecular azide-alkyne cycloaddition, providing a novel access to a variety of 8-azido-8H-[1,2,3]triazolo[5,1-a]isoindoles in high yields.
