2O (200 ml) was stirred at 30°C for 15 min before addition of glucose (0.5 g). After 15 min the keto ester (200 mg) in ethanol (1 ml) was added. After the time indicated in Table 1 the suspension was filtered through Celite pad. The filtrate was saturated with NaCl and extracted with EtOAc. The organic phase was washed with brine and concentrated. Untransformed keto ester and dihydroxy compound were purified by column chromatography.
