Reaction Steps

A mixture of 6-cyclohexylcarbamoyloxy-4-[3-(2-hydroxyethyl)-2-methyloxiranyl]-5-methoxy-1-oxaspiro[2,5]-octane (5 mg), acetic anhydride (12 μl), pyridine (11 μl), and 4-dimethylaminopyridine (1 mg) in dichloromethane (1 ml) was stirred for 1.1 hours at ambient temperature. The mixture was diluted with diethyl ether and washed with brine (4×). The organic layer was dried and concentrated in vacuo. The residue was purified by column chromatography on silica gel to yield 4-[3-(2-acetoxyethyl)-2-methyloxiranyl]-6-cyclohexylcarbamoyloxy-5-methoxy-1-oxaspiro[2,5]octane as an oil (3.7 mg).
