Abstract

In the title compound, C25H25ClO2, the C ring adopts a chair conformation, while the B ring approximates a half-chair conformation. The five-membered ring D has a twist conformation on the C—C bond fused with the C ring. Aromatic rings A and E are not coplanar, as evidenced by the dihedral angle of 7.51 (1)°. In the crystal, O—H⋯O hydrogen bonds form a double chain along the ab plane interconnected by C—H⋯O interactions.
