罗库溴铵（Rocuronium Bromide）是新的手术前的甾醇类肌松药，其安全性和有效性已得到临床研究和应用的证实. 雄甾-3，17-二醇（1）是合成罗库溴铵的关键中间体. 用硼氢化钠还原（2α，3α，5α，16β）-2，3-环氧基-16-（1-吡咯）-17-氧代雄甾烷（2），然后在吗啉和水中回流使环氧开环得到雄甾-3，17-二醇（1）. 高分辨TOF-MS质谱和1H NMR，13C NMR，1H-1H COSY，HSQC，DEPT，HMBC，2D NOESY等核磁共振谱表征确认其分子构造，并且制备和测定了雄甾-3，17-二醇1的单晶结构，确认了它的立体构型. 雄甾-3，17-二醇（1）的样品的X粉末衍射分析研究表明其衍射谱与根据单晶数据计算的理论谱一致，因此，合成的雄甾-3，17-二醇（1）的分子结构是（2β，3α，5α，16β，17β）-2-（4-吗啉基）-16-（1-吡咯）雄甾-3，17-二醇，其立体构型与罗库溴铵的立体构型一致.

Rocuronium bromide is a new neuromuscular blocking agent in clinical intervention. Its potency, specificity of action and little side effect have been confirmed. The 3,17-androstandiol (1) is a key intermediate for the preparation of rocuronium bromide. In this paper, The 3,17-androstandiol (1) was synthesized from (2α,3α,5α,16β)-2,3-epoxy-16- (1-pyrrolidinyl)-17-oxoandrostane by a reduction with sodium borohydride in methanol and then an epoxy ring opening reaction in morpholine and water. The molecular constitution was confirmed by 1H NMR, 13C NMR, 1H-1H COSY, DEPT, HSQC,HMBC, 2D NOESY and TOF-MS spectra. The single crystal of 3,17-androstandiol (1) was prepared by crystallized from 2-MeTHF and then was subjected to X-ray crystallography analysis that confirmed the stereo configuration of compound 1. And studies of X-ray powder diffractive analysis indicate that the diffractive spectrum of the sample compound 1 is consistent with the diffractive spectrum calculated on the crystal data. Therefore, the compound is (2β,3α,5α,16β,17β)- 2-(4-morpholinyl)-16-(1-pyrrolidinyl)androstan-3,17-diol and its stereochemistry is accordant with that of rocuronium bromide.
