Synthesis And Characterization

This study is concerned with the synthesis and characterization of 4-thiazolidinone derivatives (3a-3e). These compounds were prepared by reacting mercaptoacetic acid with the appropriate Schiff bases (imines) by heating at 50-60 °C in chloroform with moderate yields (51- 75 %). The structures of these 4-thiazolidinone derivatives were established on the basis of spectral studies using IR, 1H-NMR, 13C-NMR, and13C-NMR DEPT .

The reaction of(2-oxo-2H-chromen-3-Carbonyl chloride)(k1) with hydrazine in boiling ethanol gives the hydrazide(K2).When compound (k2) reacts with various aromatic aldehydes ,the corres ponding Schiff bases(k3–k4) achieve new series of thiazotidines (k5–k6) and azetidinones (k7–k8) obtained from the reactions of appropriate Schiff bases with mercapto acetic acid and chloro acetyl chloride respectively. All the compounds are characterized by FT-IR,1H-NMR and GC-Ms.
