Procedure

To a solution of 17.6 mg of 2-methylthio-5-(6-methoxycarbonylhexylidene)-4-(3-hydroxy-1-octenyl)-2-cyclopentenone obtained in Example 34 in methanol (0.5 ml) was added a solution of 2KHSO5 ·KHSO4 ·K2SO4 (27.4 mg) in water (0.2 ml) at 0° C., and the mixture was stirred for 30 minutes. To the reaction mixture were added ethyl acetate and saturated aqueous sodium hydrogencarbonate, and the product was extracted into the organic layer. The extract was washed with saturated aqueous sodium chloride, dried over anhydrous magnesium sulfate and filtered, followed by concentration. The concentrate was subjected to silica gel chromatography to obtain 3 mg (yield 16%) of 2-methylsulfinyl-5-(6-methoxycarbonylhexylidene)-4-(3-hydroxy-1-octenyl)-2-cyclopentenone.
