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

الملخص

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 .
