New Synthesis of 1H-[1,2,4]Triazolo[3,4-a]isoindoles by Intramolecular Condensation of 1-Substituted-1,2,4-triazol-4-ium Methylides

In this paper we report the first approach of synthesis of 1H-[1,2,4]triazolo[3,4-a]isoindoles in moderate to good yields by intramolecular annulation of 1-substituted-1,2,4-triazol-4-ium methylides.
