Participants

Reaction Steps

To a solution of 35 mg of 5-(1,4,7-trihydroxy-2-heptenyl)-4-hydroxy-2-methylthio-4-(4-phenoxybutyl)-2-cyclopentenone obtained in Example 72 dissolved in 2 ml of dichloromethane was added 16 mg of 3-chloroperbenzoic acid, and the mixture was stirred for 3 hours. Saturated aqueous sodium hydrogencarbonate was added, and the mixture was extracted with ethyl acetate. The organic layers were combined, washed with saturated aqueous sodium chloride, dried over anhydrous magnesium sulfate, filtered and concentrated, followed by silica gel column chromatography to give 7.3 mg (yield 46%) of 5-(1,4,7-trihydroxy-2-heptenyl)-4-hydroxy-2-methylsulfinyl-4-(4-phenoxybutyl)-2-cyclopentenone.
