الملخص EN

N- Benzylidene m-n؛trobenzeneam؛nes ( Schiff bases ) were prepared by condensation o^nitroaniline with aromatie aldehydes .

These Schiff bases were found to react with maleic anhydride to give 2-Aryl-3-( m-nitrophenyl )-2,3’ dihydro 1,3 إ] oxazepine -4,7 - diones and with phthalic anhydride to give 2-Aryl-3 - ( m- nitrophenyl ) -2,3- dihydrobenz [ 1,2-e 1,3 ] إ] oxazepine -4,7- diones which were reacted witli pyrcolidine to give the anilide - pyrrolidides of maleic acid and phthalic acid.
