摘要 用过氧乙酸把(22E,24S)-2α,3α-二羟基-5α-豆甾烷-22-烯-6-酮转化成相应的环氧化物,用液相色谱分离两种立体异构体并用核磁共振数据确定了结构,比较了3种过氧酸的反应性能. The (22E, 24S)-2α, 3α-dihydroxy-5α-stigmastan-22-en-6-one was transformed corresponding to epoxide by the peroxyacetic acid. The two epoxide isomers have been separated by liquid chromatography and their structures were identified by NMR. The activity of three peroxyacid were discussed.
