実験手順

2,3-Epoxycyclopentanone (1.0 g) and 1.06 g of 3-phenylpropyl mercaptan were dissolved in 20 ml of diethyl ether, and 20 drops of triethylamine were added. They were reacted at room temperature for 2 hours. After the reaction, the solvent was distilled off from the reaction mixture under reduced pressure. The residue (1.50 g) was chromatographed on a dry column with cyclohexane/ethyl acetate (=8/2) to afford 1.03 g of 2-(3-phenylpropylthio)cyclopent-2-en-1-one in a yield of 64%. The product had the following characteristics.
