Methyl 2-(4a,8-Dimethyl-7-oxodeca­hydro­naphthalen-2-yl)acrylate

The title compound, C(16)H(24)O(3), was isolated from the aerial part of Inula Viscosa- (L) Aiton [or Dittrichia Viscosa- (L) Greuter]. The mol-ecule contains two fused (trans) six-membered rings which both exibit a chair conformation. In the crystal, mol-ecules are linked into chains along [100] by weak C-H⋯O hydrogen bonds involving the methyl and carbonyl groups.
