Synthesis and Characterization of the 1,3- Oxazepine Derivatives

The Study Included The synthesis of some new heterocyclic compounds such as 1,3-Oxazepines from reaction between malic anhydride with Schiff bases in the precence of some drops of glacial acetic acid. Schiff-base (c1-c2) were prepared from the raction of aromatic aldehyde with aromatic amines and then reacted with maleic anhydride and phthalic Anhydride to produce new compounds 1,3- oxazepine derivatives The synthesized compounds have been characterization by the determination physical properties as such as m.p.c and the spectroscopy methods such as FlT-IR, 1H-NMR, 13C-NMR.
