Abstract

In the title compound, C(23)H(34)O(4), the C/D and D/E rings are trans fused and the A/B ring possesses an anti fusion. The two cyclo-hexane rings adopt a chair conformation while the cyclo-hexene ring exhibits a half-chair conformation. The cyclo-pentane ring displays an envelope conformation with the C atom bearing the methyl group as the flap. In the crystal, the mol-ecules are linked by O-H⋯O hydrogen bonds, forming chains along the b axis.
