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 from alcohols has been carried out for the first time. Mild reaction conditions, wide functional group tolerance, ease of work-up, and good
据报道,丙基膦酸酐(T3P®)-DMSO介导的醇氧化为羰基化合物,随后将其与芳基/杂芳基胺和巯基乙酸环化,得到4-噻唑烷酮。首次直接从醇类合成4-噻唑烷酮。温和的反应条件,宽泛的官能团耐受性,简便的后处理和良好的收率是该方案的显着特征。
