Abstract A pregnane-3,6,20-triol isomer has been isolated from hydrolysed urine. In order to identify this compound and to facilitate further study four pregnane-3,6,20β-triol isomers have been synthesised starting from 3α,6α-dihydroxy-5β-pregnan-20-one. Gas chromatographic and mass spectrometric data have been recorded for these compounds and also g.l.c. data for the corresponding 20α-isomers. The
摘要 从
水解尿液中分离出一种孕烷-3,6,20-三醇异构体。为了鉴定该化合物并促进进一步研究,从 3α,6α-dihydroxy-5β-pregnan-20-one 开始合成了四种孕烷-3,6,20β-三醇异构体。已经记录了这些化合物的气相色谱和质谱数据以及相应 20α-异构体的 glc 数据。后者与相应的 20β-异构体、17α-20-酮和起始材料一起通过 20-酮的非选择性还原获得。
