실험 절차

To a solution of 71 mg of 5-[(E)-4,7-dihydroxy-2-heptenylidene]-4-hydroxy-2-methylthio-4-(4-phenoxybutyl)-2-cyclopentenone obtained in Example 91 dissolved in 2 ml of dichloromethane was added a solution of 45 mg of 3-chloroperbenzoic acid in 2 ml of dichloromethane, and the mixture was stirred for 3 hours. Saturated aqueous sodium hydrogencarbonate was added. The mixture was extracted twice with ethyl acetate, and the organic layers were combined, washed with saturated aqueous sodium chloride and dried over anhydrous sodium sulfate. After filtration and concentration, the concentrate was subjected to silica gel column chromatography to give 27 mg (yield 38%) of low polarity isomer and 25 mg (yield 35%) of high polarity isomer of 5-[(E)-4,7-dihydroxyheptenylidene]-4-hydroxy-2-methylsulfinyl-4-(4-phenoxybutyl)-2-cyclopentenone.
