Procedure

To a solution of 165 mg of 5-[(E)-4,7-dihydroxyheptenylidene]-4-hydroxy-2-methylsulfinyl-4-(4-phenoxybutyl)-2-cyclopentenone obtained in Example 104 dissolved in 30 ml of dichloromethane was added a solution 117 mg of 3-chloroperbenzoic acid in 5 ml of dichloromethane, and the mixture was stirred for 2 hours. The reaction mixture was poured onto saturated aqueous sodium thiosulfate, and the mixture was extracted 3 times with ethyl acetate. The organic layers were combined, washed twice with saturated aqueous sodium hydrogencarbonate and with saturated aqueous sodium chloride, and dried over anhydrous sodium sulfate. After filtration and concentration, the concentrate was subjected to chromatography to give 78 mg (yield 47%) of 5-[(E)-4,7-dihydroxy-2-heptenylidene]-4-hydroxy-2-methylsulfonyl-4-(4-phenoxybutyl)-2cyclopentenone
