Crystal structure of cholest-5-en-3β-yl 3-(2,4-dimeth-oxy-3-methyl-phen-yl)prop-2-enoate.

In the title compound, C39H58O4, the steroid rings A and C adopt a chair conformation, while ring B adopts a half-chair conformation, and ring D has an envelope conformation, with the methyl-substituted C atom as the flap. In the crystal, mol-ecules pack within layers parallel to (100), with their long axis parallel to the [101] direction. Adjacent layers are linked via C-H⋯O hydrogen bonds and C-H⋯π inter-actions, forming a three-dimensional framework.
