SYNTHESIS OF NEW 5-BROMO-1H-INDOLE-2,3-DIONE DERIVATIVES BY 1,3-DIPOLAR CYCLOADDITION

To contribute to the development of the chemistry of 5-bromo-isatin, we have synthesized new heterocyclic systems, using alkylation reactions under conditions of phase transfer catalysis to be then subjected to cycloaddition reactions dipolar involving 1,3-dipoles. The structures of the various products obtained were determined by 1H NMR, 13C NMR spectroscopy.
