Synthesis And Characterization Of Some New Five Membering Ring Compounds Such As Thiazolidinones and γ -Lactams

This study concerned with the synthesis and characterization of   thiazolidinones & γ- lactams , the thiazolidinones compounds are prepared from A mixture of Schiff base (Imine) and thioglycolic acid, γ- lactams compounds are prepared from A mixture of Schiff base (Imine) with phenylsuccinic anhydride  in moderate yields (52-71 %). The structures of these  thiazolidinones and  γ-lactams were  established on the basis of the spectral  data namely IR, 1H-NMR,13C-NMR, 13C-NMR DEPT , Mass spectra
