7-Hydroxy-8-isopropyl-1,1,4a-trimethyl-4a,9,10,10a-tetrahydro-phenanthren-2(1H)-one

The title compound, C20H26O2, was isolated from a chloroform extract of Tetraclinis articulata wood. The molecule contains three fused rings which exhibit different conformations. The non-aromatic oxo-substituted ring has a screw-boat conformation, while the central ring has a half-chair conformation. In the crystal, molecules are linked to each other by intermolecular O—H...O hydrogen bonds involving the carbonyl and hydroxy groups.
