利用三异丁基硼氢化锂（L-selectride）试剂还原3-氧代-22-羟基何伯烷得到单一构型的3α，22-二羟基何伯烷和3β，22-二羟基何伯烷.在此基础上，通过X-射线单晶衍射实验确认了3β，22-二羟基何伯烷的绝对构型，并完整归属了该类化合物的1H和13C NMR数据.本文的方法亦可用以制备其他使用常规方法难以分离的α-和β-异构体.

Pure α- and β- isomers of 3, 22-dihydroxyhopane were obtained by the reduction of hydroxyl protected hydroxyhopanone with L-selectride. The absolute configuration of 3β, 22-hydroxyhopane was confirmed by single crystal X-ray diffraction, and the unambiguous 1H and 13C NMR data of two isomers were fully assigned for the first time. The preparation method is suitable for the separation of other unseparated α, β-isomers.
