PREPARATION AND CHARACTERIZATION OF SOME NEW OXAZEPINE COMPOUNDS

Natiq G. Ahmed, Hussein Y. Al-Hashimi.

Abstract
The ketonic compound (1) is synthesized from equal moles of morpholine, 4-nitrobenzaldehyde, and 3-nitro acetophenone. Schiff base
compounds (2)-(4), prepared by reacting (1) with different aromatic amines (4-aminoantipyrine, p-phenylenediamine, 2-aminopyridine),
contain a set of one or more of azomethine (-C=N-) groups that have been used in the preparation of many heterocyclic compounds, which
when reacted with maleic anhydride give 1,3-oxazepine compounds (a ring with seven atoms) (5)-(7), and seven membered ring
benzo[1,3]oxazepine compounds (8)-(10) are obtained by reaction with phthalic anhydride. The synthesized compounds are identified
using physical (melting points, colour change, thin layer chromatography) and spectral methods such as IR, UV, and NMR spectra). The
biological effectiveness of some of the prepared compounds is measured.

Key words: Mannich bases, Schiff bases, oxazepines; benzo[1,3]oxazepines.
