PROCEDURE

实验过程

According to Scheme 1, (25R)-16β-26-dihydroxycholesterol (2), prepared in one step from diosgenin, is selectively reacted at the C-26 hydroxyl group with p-toluene sulfonyl chloride to yield (25R)-16β-26-dihydroxycholesterol 26-tosylate (3) which is then reacted with potassium phthalimide. The resulting (25R)-16β-hydroxy-26-phthalimidocholesterol (4) is then subjected to a modified Jones oxidation which selectively oxidizes the 16β hydroxy group to form (25R)-16-oxo-26-phthalimidocholesterol (5).
