실험 절차

2,3-Epoxycyclopentanone (1.47 g) and 2.0 g of 2-hydroxy-2-methylheptyl mercaptan were dissolved in 30 ml of diethyl ether, and 30 drops of triethylamine were added. They were reacted at room temperature for 2 hours. The solvent was distilled off from the reaction mixture to afford 4.01 g of a crude product. The crude product was chromatographed on a dry column with cyclohexane/ethyl acetate (=8/2) to afford 2.07 g of 2-(2-hydroxy-2-methylheptylthio)cyclopent-2-en-1-one in a yield of 69%. The product had the following characteristics.
