摘要 7-羰基化合物的立体选择性还原是合成熊去氧胆酸的关键.本文以易得的豆甾醇(1)经一系列转 化得到7-羰基豆甾烷-3-乙酸酯(3),并首次用一种国内外在合成熊去氧胆酸的还原方法中尚未采用的方 法立体选择性还原化合物(3),从而制备了合成UDCA的重要前体化合物(4). Stereoselective reduction of 7-keto compound is a key to preparation of Ursodeoxycholic acid. A new reductive method was carried out to preparation of important precursor of UDCA by reduction of 7- ketostigmasterane- 3- acetate.
