Acetic Acid → alpha-Mercaptomethyl-beta-phenyl-gamma-butyrolactone

참여 물질

반응 단계

To a solution of 1.0 g of α-methanesulfonyloxymethyl-β-phenyl-γ-butyrolactone (III) in 20 ml of ethanol were added 1.5 ml of acetic acid and then 1.2 g of commercially available 70% sodium hydrosulfide and the mixture was stirred at room temperature for 18 hours. After completion of the reaction, the reaction mixture was diluted with 150 ml of ethyl acetate, washed with water in a conventional manner, dried over magnesium sulfate and the solvent was distilled off. The crude product thus obtained was purified by a column chromatography to give 400 mg (yield 52%) of the title compound.
