Abstract

This research includes , synthesis of new heterocyclic derivatives,and the first step Involves preparation of chalcone compounds through a reaction between m-amino acetophenone with p-chloro benzaldehyde and p-nitro benzaldehyde which is then used for preparation of new chalcones ,the second step of this study leads for preparation of new shiff bassesThe last step includes preparation of thiazine , oxazine , isoxazole and pyrazole derivatives..Thin layer cromotography was used to follow the reactionsAll the compounds have been characterized by melting points and FT-IR Spectroscopy, some of them characterized by (H1-NMR)-spectra and Elemental Analysis(C.H.N).
