converted in near quantitative yield (based on the utilization of the (3S) enantiomer) to 21-hydroxylanosterol using a Baker's yeast suspension. Similarly, 26-hydroxy-2,3-oxidosqualene is efficiently cyclized to 19-hydroxylanosterol.
使用贝克酵母悬浮液将29-羟基-2,3-氧化角鲨烯以接近定量的产率(基于(3 S)对映异构体的利用)转化为21-羟基羊毛甾醇。类似地,26-羟基-2,3-氧化角鲨烯被有效地环化为19-羟基羊毛甾醇。
