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.

In the title compound, C22H29NO3, 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. The heterocyclic ring adopts a 14β-sofa conformation. The butyl substituent is nearly planar, this plane lying almost perpendicular to the least-squares plane of the heterocyclic ring. Inter­molecular O—H...O hydrogen bonds link the mol­ecules into extended chains and the compound also exhibits some weak inter­molecular C—H...O inter­actions.
