Title: | 6β-Chloro-5α-hydr-oxy-20-oxopregnan-3β-yl acetate | Authors: | Pinto, Rui M. A. Salvador, J. A. R. Paixão, J. A. Beja, Ana Matos Silva, Manuela Ramos |
Issue Date: | 5-Jul-2008 | Publisher: | International Union of Crystallography | Serial title, monograph or event: | Acta Crystallographica Section E: Structure Reports Online | Volume: | 64 | Issue: | Pt 8 | Abstract: | The title steroid, C(23)H(35)ClO(4), is a pregnane derivative prepared by ring opening of the corresponding 5α,6α-ep-oxy steroid with BiCl(3). There are two symmetry-independent mol-ecules in the asymmetric unit that show no significant differences concerning bond lengths and angles. The conformation of the six-membered rings in both mol-ecules is close to a chair form, while the five-membered ring adopts an envelope conformation. All rings in both mol-ecules are trans-fused. The mol-ecules are held together by an extensive O-H⋯O hydrogen-bonding network. | URI: | https://hdl.handle.net/10316/110437 | ISSN: | 1600-5368 | DOI: | 10.1107/S1600536808019478 | Rights: | openAccess |
