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.
