Abstract:
In this paper a series of 1,3-oxazepine derivatives have been synthesized through out two pathways.first one synthesis of imines derivatives (w1-w4) by the condensation reaction of different substituted aldehyde such as (p-N,N-dimethylamino , p- N ,N –diethyl amino , p-chloro, and p-bromo)benzaldehyde with unsubstantiated  Benzidine .while the second pathway involve reactions of the prepared imines (w1-w4) via maleic and phthalic anhydride under inert N2 gas and refluxing conditions to produce 1,3- oxazepine -4,7-dione derivatives (w1m-w4m and w1ph –w4ph) respectively . All the compounds were monitored and elucidated by TLC and available spectroscopic tools such as IR and Elemental analysis .

Key words: imines, benzylidene and 1, 3-oxazepine-4,7-dione :
