Sucesseful approache for the synthesis of newly fused heterocyclic compounds incorporating phenylperinaphthenone and naphrydine derivatives.

The reacion of 3- cyano-4-methyl-6-oxo-5-phenylhydrazono-2-pyridinylmalono- nitrile 1 with a different substituted of alpha, beta -unsaturated nitriles : hydrazines: hydroxylaminehydrochloride; phenylisocyanate: a mixture of hy drochloric / acetic acid and with sulfur afforded the corresponding newly f used heterocyclic azines. The structures of these compounds were establishe d by analytical and spectral data.
