Reaction Steps

To a solution of 21.9 mg of 2-methylthio-5-(6-methoxycarbonylhexylidene)-4-(3-hydroxy-1-octenyl)-2-cyclopentenone obtained in Example 544 in methanol (3 ml) was added a solution of sodium metaperiodide (118.7 mg) in water (0.5 ml), and the mixture was stirred for 18 hours. To the reaction mixture were added ethyl acetate and saturated aqueous sodium chloride, 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 give 9.6 mg (yield 42%) of 2-methylsulfinyl-5-(6-methoxycarbonylhexylidene)-4-(3-hydroxy-1-octenyl)-2-cyclopentenone.
