This study is concerned with the synthesis and characterization of γ-lactams 3a-3h. These compounds were prepared by reacting
phenylsuccinic anhydride with the appropriate Schiff bases (imines) 2a-2h by heating at 51-61 ˚C in chloroform with moderate yields (70-
92 %). The structures of these γ-lactams were established on the basis of the spectral studies using IR, 1H-NMR,13C-NMR, HSQC 1H13CNMR, and MS
Key words: γ-lactams, cycloaddition, imines, NMR.
