title: (1R,3aR,5aS,6S,8aR,8bR,9aS)-1-Hydr-oxy-6-isopropyl-1,3a,5a-trimethyl-perhydro-cyclo-penta-[a]cyclo-propa[i]naphthalen-4-one.
abstract: The title compound (also know as azorellanone), C(20)H(32)O(2), is built up from three fused carbocycles, one five-membered ring and two six-membered rings. The five membered-ring has an envelope conformation, whereas the six-membered rings have a distorted half-chair and a twist-boat conformation. In the crystal, mol-ecules are linked by O-H⋯O inter-actions into zigzag chains with graph-set notation C(8) along [010]. The absolute configuration was assigned on the basis of earlier chemical studies.
