Abstract: In the title compound, C23H27NO4, a modified synthetic D-homo steroid, the cyclohexene ring adjacent to the aromatic ring adopts a half-chair conformation, while the cyclohexane ring has an ideal chair conformation and the heterocyclic ring has a sofa conformation. The plane of the allyl substituent lies almost perpendicular to the least-squares plane of the heterocyclic ring. The crystal structure contains a series of weak C-H...O intermolecular interactions.
