6-Substituted 1-hetarylamino-3-aryloxindoles
Abstract6-Substituted 1-hetarylamino-3-aryl-2,3-dihydro-2-indolones were obtained by cyclization of diarylglycolic acid hetarylhydrazides in concentrated H2SO4. The ability of the compounds obtained to undergo acylation was demonstrated. A cyclization mechanism is proposed. The IR, PMR, and mass spectra of the synthesized compounds were studied.
