Abstract
In the asymmetric unit of the title compound, C38H56O3, there are two symmetry-independent molecules that differ in the rotation angle along the C—O bond between the 3-(4-ethoxyphenyl)prop-2-enoate and cholest-5-en-3β-yl groups by 169.3 (3)°. In both molecules, 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 molecules pack in the crystal into separate layers parallel to (-102) with their long axis parallel to the [201] direction. Short intermolecular C—H⋯O and C—H⋯π contacts are observed.
