3-[4-(Dimethylamino)phenyl]-1-(4a,8-dimethyl-1,2,3,4,4a,5,6, 8a-octahydronaphthalen-2-yl)prop-2-en-1-one

Abstract

The title compound, C23H31NO, was semisynthesized from isocostic acid, 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. The dihedral angle between the latter ring and its substituent is 83.6 (7)°.
