الملخص العربي
The present work included condensation reaction s of o-tolidine with
Different aromatic aldehydes in absolute ethanol to give Schiff bases (w9–w12) 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 (w9m–w12m) and [1,3]oxazepine -1,5- dione (w9ph–
w12ph), 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.
