Synthesis, Characterization of Some New Heterocyclic Derivatives

Abstract

The newly compounds containing a seven-member ring oxazepane and five-member ring tetrazole derivatives were prepared starting schiff bases. Synthesized by percyclic reactions of imine group with phthalic anhydride resulted the formation of 1,3-oxazepane-4,7dione derivatives (S₁, O). The new tetrazole derivatives were obtained from treatment of each prepared schiff bases S and S₁ with sodium azide to give derivatives (S₂, T). Finally derivatives have been characterized by melting points, FT.IR and ¹H-NMR spectroscopy.

Keywords: Phathalic anhydride, Sodium azide, Tetrazole, Oxazepane-4,7dione.
