title: Crystal structure of 3a,6,6,9a-tetra-methyl-dodeca-hydro-naphtho-[2,1-b]furan-2-ol.
abstract: The title compound (common name: sclaral), C16H28O2, is a sclareolide derivative, which was synthesized from sclareolide itself. In the mol-ecule, the two six-membered rings, A and B, of the labdane skeleton adopt chair conformations and the five-membered O-containing heterocyclic ring C displays an envelope conformation, with the methine C atom of the fused C-C bond as the flap. In the crystal, mol-ecules are linked by O-H⋯O hydrogen bonds, forming chains propagating along [100].
