Abstract

In the asymmetric unit of the title compound, C(38)H(56)O(3), there are two symmetry-independent mol-ecules that differ in the rotation angle along the C-O bond between the 3-(4-eth-oxy-phen-yl)prop-2-enoate and cholest-5-en-3β-yl groups by 169.3 (3)°. In both mol-ecules, steroid ring B adopts a half-chair conformation, rings A and C adopt a chair conformation and ring D exists in an envelope form. The two symmetry-independent mol-ecules pack in the crystal into separate layers parallel to (-102) with their long axis parallel to the [201] direction. Short inter-molecular C-H⋯O and C-H⋯π contacts are observed.
