Abstract: The behaviour of some alpha,beta-unsaturated ketones or beta-diketones, derived from quinolones, naphthyridinones or a combination of both of them, towards amines, diamines, and other ammonia derivatives at different ratios and conditions had been studied; the result were many interesting polyheterocyclic compounds containing either quinolone, naphthyridinone or both as the main moiety besides the recently formed hetero rings as: diazepine, oxazepine, thiazepine, triazepine, thiazole, thiazoline, pyrazoline, isooxazoline, pyrimidine, indole, triazinoindole, and quinoxaline. The structures of the resulting new polyheterocyclic compounds were established by chemical reactions, elemental analysis, and spectral data.
