The modern Microwave technique used to synthesis new derivatives of 1,3 – Oxazepine – 4 , 7 - dione, compounds

Abstract

In this search, we take the direct reaction line between the aromatic aldehydes & aromatics ammines for reaction in Microwave technique to obtain clean and safe chemistry with very short time and high products, high purity comparative with the thermal method (Reflux). The above compounds allowed to reaction to produce (hydrazon) or which named (Schiff bases) compounds (1, 3, 5, 7, 9). The last step is cyclization step by irradiation with Microwave too, by reaction between hydrazon compounds, and phthalic anhydride to produce the (1, 3 – Oxazepine) new derivatives (2, 4, 6, 8, 10) as a final compounds, which employed in medical and pharmaceutical research’s. The prepared compounds were identified using melting point apparatus, Infrared Spectroscopy; the results are agreement with the proposed assigned to the synthesized compounds.
