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-H⋯O hydrogen bonds.
标题化合物C₁₅H₂₀O₅呈现出一种双降倍半萜骨架,其反式十氢化萘主链由内酯桥限制。属于两个十氢化萘环的α-羟基取代基和甲基处于轴向位置,而另一个甲基和酰基占据空间上更有利的赤道位置。分子结构通过分子内C-H⋯O氢键得以稳定。在晶体中,分子通过O-H⋯O氢键沿[010]方向连接成链。
