Abstract

Various types of heterocyclic seven membered rings were prepared from the reaction of 2,3Pyridine caroboxylic anhydride with Schiff bases (which was prepared using different Aldehydes with amines [H1-H10] and seven membered rings were prepared (derivatives of 7,8-dihydropyrido[2,3e][1,3]oxazepine-5,9-dione, and the presence of Aceton. [A1-A10].         Melting points of the compounds were measured. The prepared compounds were diagnosed spectrally by using UV-Visible and Infrared spectroscopy, and (1H-NMR) Spectrum for some compounds. The results confirmed the validity of the proposed chemical compositions.
