Reaction Steps

A mixture of (5α,25R)-spirost-1-en-3-one (2.87 g, 6.96 mmol), tetrahydrofuran (30 mL), methanol (50 mL) and 15% sodium hydroxide (1 mL) was stirred under nitrogen atmosphere. The mixture was cooled to 0° C. and 30% hydrogen peroxide (5 mL) was added. The reaction mixture was gradually warmed to room temperature and stirred for 4 hours. The reaction was diluted with ethyl acetate, cooled to 0° C., and then quenched with saturated sodium bisulfite solution. The mixture was washed with saturated sodium bisulfite (2×), brine (1×), dried (sodium sulfate), filtered and concentrated in vacuo to give 2.64 g, (88%) of the title compound.
