Abstract

A highly efficient and versatile method for the synthesis of quinoxaline derivatives with two benzimidazole fragments have been developed on the basis of the ring contraction of 3- (benzimidazo-2-yl) quinoxalin-2 (1H)-one with 1, 2-diaminobenzene and its various types of substituted and condensed derivatives. Owing to the inter-and intramolecular processes, involving self association, proton exchange, conformational, and/or tautomeric exchanges ...
