1-(4a,8-Dimethyl-1,2,3,4,4a,5,6,8a-octahydronaphthalen-2-yl)-3-(4-methylphenyl)prop-2-en-1-one

Abstract

The title compound, C22H28O, was isolated from the aerial part of Inula viscosa (L) Aiton [or Dittrichia viscosa (L) Greuter]. The cyclohexene ring has a half-chair conformation, whereas the cyclohexane ring displays a chair conformation being substituted at position 2 by a 3-(4-methylphenyl)prop-2-enoyl group. In the crystal, weak intermolecular C—H...O hydrogen bonds link molecules into chains in the [010] direction.
