Synthesis and identification of some new thiazin and oxazin compounds and new derived from chalcones

Abstract

Abstract This research deals with preparing a new hetero cyclic compounds through two parts: The first part of this study includes preparation of new (Chalcone) Compounds through condensation reaction of aryl ketones with aromatic aldehyde .The second part includes synthesis of new hetero cyclic compounds( Oxazin and Thiazin) through cyclization of the prepared compounds in the first part with Urea and Thiourea . Thin Layer Chromatography was used to follow the chemical reaction and to Characterize the new derivatives by using FT- IR ,C.H. N and H- NMR techniques , the Results proved correctiness of the chemical structures of the prepard derivatives .
