| Abstract: | The present work included condensation reactions of o-tolidine with different aromatic aldehydes in absolute ethanol to give Schiff bases (w 9 –w 12 ) in high yield which, on reaction with maleic and phthalic anhydride by 2+5] cycloaddition reactions in the presence of suitable solvents, give the corresponding 1,3]oxazepine-4,7-dione (w 9 m–w 12 m) and 1,3]oxazepine-1,5-dione (w 9 ph–w 12 ph), respectively. The structure of the newly synthesized compounds were monitored by TLC and established on the basis of elemental analysis, FT-IR, and 1H NMR. |
