7-Hy-droxy-8-isopropyl-1,1,4a-trimethyl-4a,9,10,10a-tetra-hydro-phenanthren-2(1H)-one.

ABSTRACT: The title compound, C(20)H(26)O(2), was isolated from a chloro-form extract of Tetra-clinis articulata wood. The mol-ecule 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, mol-ecules are linked to each other by inter-molecular O-H⋯O hydrogen bonds involving the carbonyl and hy-droxy groups.
