SYNTHESIS AND CHARACTERIZATION OF NOVEL 1,3-OXAZEPANE DERIVATIVES VIA REACTION OF PHENYI SUCCINIC ANHYDRIDE WITH SCHHIF'S BASES

Abstract

Novel 1,3-oxazepane-4,7-dione derivatives were synthesized by the reaction of phenyl succinic anhydride with Schiff‘s bases in anhydrous benzen with high yields. Schiff's bases were synthesized by the reaction of heteroaromatic aldehydes or ketones with primary heterocyclic amines. The resulting products were identified by their melting point and their molecular structures were confirmed by FT-IR , UV-Vis. and 1HNMR spectroscopy.
