Abstract

The reactions of 2-(2-aminophenyl)benzimidazole with substituted isatins afforded the corresponding 5,6-dihydrospiro(benz[4,5]imidazo[1,2-c]quinazoline-6,3′indolin)-2′-ones. The spirocyclic structure of the reaction products was established by NMR spectroscopy and X ray diffraction analysis.
