[figure: see text] (+)-Arnicenone, a sesquiterpene of an angular triquinane isolated from Arnica plants, has been synthesized for the first time in an enantiocontrolled manner from a synthetic equivalent of chiral 2-hydroxymethylcyclopentadienone to determine the absolute configuration of the natural product as 1R,3aR,5aS,8aR.
