Synthesis, Characterization and Evaluate the Biological Activity of Novel Heterocyclic Derivatives from Azomethine Compounds

This research includes synthesis of new seventh-membered heterocyclic derivatives as 1,3-oxazepine-dione derived from azomethine compounds. Azomethine compounds R1-R4 were synthesized by the reaction of aromatic aldehydes with primary aromatic amines. The novel of 1,3-oxazepine-dione derivatives R5-R9 were obtained from the treatment of azomethine compounds with anhydrides. The synthesized compounds were checked by TLC technique, spectral methods (FT-IR, H1-NMR) and measurements of some its physical properties. The biological activity of the heterocyclic derivatives was investigated against bacteria and fungi in vitro.
