SYNTHESIS OF BENZO[c][1,7]NAPHTHYRIDINE DERIVATIVES

Abstract
Reactivity of 2-methyl-6-phenylbenzo[c][1,7]naphthyridine in alkylation, oxidation, and electrophilic substitution reactions has been studied. The reaction of 2-methyl-6-phenylbenzo[c][1,7]naphthyridines with POCl3 yielded the previously unknown 4-chloro-2-methyl-6-phenylbenzo[c]-[1,7]naphthyridine. Its dehalogenation and substitution of halogen by nitrogen and sulfur nucleophiles were studied.
Keywords
