SYNTHESIS AND CHARACTERIZATION OF TWO MOIETIES OF-1,3- OXAZEPINE-1,5-DIONE COMPOUNDS VIA 4,4'- DIAMINODIPHENYLMETHANE IMINES AS PRECURSORS

Abstract

New derivatives of 1,3-oxazepine(1b–7b)(1c–7c) were synthesized by the reaction of Schiff bases (1a–7a) with Succinicand Maleic anhydrideusing dry benzene as a solvent. Schiff bases (1a–7a)were prepared by condensation of 4,4'- Diaminodiphenylmethanewith methoxy and halobenzaldehydeusing absolute ethanol as a solvent in the presence of glacial acetic acid as a catalyst. All synthesized compounds were monitored by TLC and characterized using spectroscopy techniques such as (FT-IR), (1H-NMR) and (13C-NMR), they revealed that all synthesized compounds were conformity of the proposed structures.
