(1R,2S,4S,4aS,8S,8aS)-4-Hy-droxy-8,8a-dimethyl-10-oxo-2,3,4,7,8,8a-hexa-hydro-1H-4a,1-(ep-oxy-methano)-naphthalen-2-yl acetate.

ABSTRACT: The title compound, C15H20O5, presents a bis-norsesquiterpene skeleton, with a trans-deca-line backbone constrained by the lactone bridge. The ?-hy-droxy substituent and the methyl group belonging to the two deca-line rings are in axial positions, whereas the other methyl group and the acyl group occupy the sterically preferred equatorial positions. The mol-ecular structure is stabilized by an intra-molecular C-H?O hydrogen bond. In the crystal, mol-ecules are linked into chains along [010] by O-H?O hydrogen bonds.

The title compound, C15H20O5, presents a bis-norsesquiterpene skeleton, with a trans-deca-line backbone constrained by the lactone bridge. The α-hy-droxy substituent and the methyl group belonging to the two deca-line rings are in axial positions, whereas the other methyl group and the acyl group occupy the sterically preferred equatorial positions. The mol-ecular structure is stabilized by an intra-molecular C-H⋯O hydrogen bond. In the crystal, mol-ecules are linked into chains along [010] by O  ...[more]
