Reaction Steps

To a solution of 5-methoxy-4-[2-methyl-3-(3-methyl-2-butenyl)oxiranyl]-6-(thiomorpholin-4-ylcarbonyloxy)-1-oxaspiro[2,5]octane (41 mg) in 1,4-dioxane (2 ml) and water (0.2 ml) was added sodium periodate (21 mg) at ambient temperature. After stirring at the same temperature for 18 hours, the reaction mixture was diluted with diethyl ether. The precipitates were filtered off by celite and the filtrate was concentrated in vacuo. The residue was purified by column chromatography on silica gel (elution by ethyl acetate) to yield 5-methoxy-4-[2-methyl-3-(3-methyl-2-butenyl)oxiranyl]-6-(1-oxothiomorpholin-4-ylcarbonyloxy)-1-oxaspiro[2,5]octane (25 mg) as an oil.
