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

Abstract

The title compound, C16H24O3, was isolated from the aerial part of Inula Viscosa (L) Aiton [or Dittrichia Viscosa (L) Greuter]. The molecule contains two fused (trans) six-membered rings which both exibit a chair conformation. In the crystal, molecules are linked into chains along [100] by weak C—H...O hydrogen bonds involving the methyl and carbonyl groups.
