Reaction Steps

The 3-(1,3-dihydro-6-methoxy-7-methyl-3-oxo-4-p-toluenesulfonyloxy-5-isobenzofuranylmethyl)-1-methylcyclopent-2-en-1-ylacetaldehyde was dissolved in dioxane (8 mL) and pH 5 buffer (3 mL) and treated with resorcinol (0.10 g). To this mixture was then added sodium chlorite (0.080 g). After 2 minutes, the reaction was diluted with ethyl acetate and made acidic with 5% hydrochloric acid. After two extractions with ethyl acetate, the combined organic layers were dried over magnesium sulfate. The residue, 3-(1,3-dihydro-6-methoxy-7-methyl-3-oxo-4-p-toluenesulfonyloxy-5-isobenzofuranylmethyl)-1-methylcyclopent-2-en-1-ylacetic acid obtained after solvent removal was carried on without further purification.
