実験手順
To a mixture of 3α-acetoxy-12α-(2,2-dimethyl)butyryloxy-5β-chola-8(14),23-diene (2.5 g), osmium tetroxide (0.092 g), tert-butyl alcohol (8 ml), and water (2.3 ml) is added 4-methylmorpholine-N-oxide hydrate (0.334 g). The mixture is stirred for about 2 hours at room temperature, diluted with 20% ethyl acetate in ether and washed with aqueous sodium bisulfite. The organic solution is dried over magnesium sulfate, filtered and concentrated in vacuo to give the desired product which is used, without further treatment, for the next step.
