(1R,2S,4S,4aS,8S,8aS)-4-Hydroxy-8,8a-dimethyl-10-oxo-2,3,4,7,8,8a-hexahydro-1H-4a,1-(epoxymethano)naphthalen-2-yl acetate

Abstract

The title compound, C15H20O5, presents a bis­norsesquiterpene skeleton, with a trans-deca­line backbone constrained by the lactone bridge. The α-hy­droxy substituent and the methyl group belonging to the two deca­line rings are in axial positions, whereas the other methyl group and the acyl group occupy the sterically preferred equatorial positions. The mol­ecular structure is stabilized by an intra­molecular C—H⋯O hydrogen bond. In the crystal, mol­ecules are linked into chains along [010] by O—H⋯O hydrogen bonds
