Structure and absolute configuration of parodiolide, a new dimeric sesquiterpene lactone isolated from Mikania parodii Cabrera possessing an uncommon spiro connexion

The title compound, C15H20O3, a sesquiterpene lactone, was isolated from the aerial parts ofCarpesium minusHemsl. (Compositae). The molecule is composed of three rings, with the two cyclohexane rings in chair conformations and the cyclopentane ring adopting a twist conformation. TheA/Bring junction istrans-fused. The absolute configuration shown has been arbitrarily assigned. In the crystal, molecules are linked into [100] chains by O—H...O hydrogen bonds.
