The title steroid, C(23)H(35)ClO(4), is a pregnane derivative prepared by ring opening of the corresponding 5α,6α-epoxy steroid with BiCl(3). There are two symmetry-independent molecules in the asymmetric unit that show no significant differences concerning bond lengths and angles. The conformatio...

description | The title steroid, C(23)H(35)ClO(4), is a pregnane derivative prepared by ring opening of the corresponding 5α,6α-epoxy steroid with BiCl(3). There are two symmetry-independent molecules in the asymmetric unit that show no significant differences concerning bond lengths and angles. The conformation of the six-membered rings in both molecules is close to a chair form, while the five-membered ring adopts an envelope conformation. All rings in both molecules are trans-fused. The molecules are held together by an extensive O—H⋯O hydrogen-bonding network. |
