The synthesis of N-alkoxycarbonyl and N-carboxamide derivatives of anti-inflammatory oxindoles is described. These compounds, sought as potential prodrugs of the parent anti-inflammatory agents, were obtained by ring opening of the oxadiazine dione intermediates formed by the treatment of 1-unsubstituted 3-acyloxindoles with chlorocarbonyl isocyanate.
