Cholest-5-en-3β-yl 3-(4-eth­oxy­phen­yl)prop-2-enoate

In the asymmetric unit of the title compound, C(38)H(56)O(3), 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 hal...

Sumario:In the asymmetric unit of the title compound, C(38)H(56)O(3), 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.
