With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.185137-29-5,(S)-4-Phenylthiazolidine-2-thione,as a common compound, the synthetic route is as follows.,185137-29-5
General procedure: To thiazolidine-2-thiones (1.0 equiv.) in THF (5.5 mL/mmol), 60% NaH dispersion in mineral oil (1.2 equiv.)was slowly added at 0 C. The reaction mixture was stirred for 15 min at 0 C before acetyl chloride (1.2 equiv.)was added dropwise. The reaction mixture was stirred for 30 min at 0 C, upon which it was warmed to roomtemperature and allowed to stir for another 2 h. The reaction was quenched with saturated NH4Cl (3 mL/mmol)and the layers were separated. The aq. layer was extracted with EtOAc (2 x 4 mL/mmol) and the combinedorganic layers were dried (Na2SO4),filtered, and concentrated in vacuo. The crude product was purified bycolumn chromatography on silica (hexanes/EtOAc 8:2) to afford the title compounds as yellow oils.
As the paragraph descriping shows that 185137-29-5 is playing an increasingly important role.
