Propylphosphonic anhydride (T3P®)-DMSO mediated oxidation of alcohols to carbonyl compounds and their subsequent cyclization with aryl/hetero aryl amines and thioglycolic acid to afford 4-thiazolidinones has been reported. Synthesis of 4-thiazolidinones directly fromalcohols has been carried out for the first time. Mild reaction conditions, wide functional group tolerance, ease of work-up, and good
