Chemistry of Heterocyclic Compounds Aims and scope

Abstract

New heterocyclic systems, viz., 3H,8H-indolo[4,5-e]indole and 3H,8H-indolo-[5,4-e]indole, which were also obtained from the corresponding pyruvic acid dihydrazones, were synthesized by cyclization of ethyl pyruvate 2,7- and 2,6-naphthylenedihydrazones and subsequent saponification and decarboxylation of the cyclization products. The syn-syn, syn-anti, and anti-anti forms of the dihydrazones were isolated and characterized.
