Beattie, Karren D. and Bhadbhade, Mohan M. and Craig, Donald C. and Leach, David N. (2012) (3R,4S,5S,8S,10R,13R)-3-Hydroxykaura-9(11),16-dien-18-oic acid. Acta Crystallographica Section E: Structure Reports Online, 68 (2). o526-o527.

Abstract

The title compound, C(20)​H(28)​O(3)​, was isolated during our investigation into the chemical composition and pharmacological activity of Centipeda cunninghamii (DC.) A. Braun & Asch. (Asteraceae)​. The enanti-​opure compound, a diterpene with a carbon skeleton, is composed of three six- and one five-​membered rings in chair, twist-​boat, half-​chair and envelope conformations, respectively. Each mol-​ecule makes one intra- and one inter-​molecular O-​H(midline ellipsis)​O hydrogen bond in the crystal lattice, forming hydrogen-​bonded chains along [010]​. The absolute configuration of the compound was assigned on the basis of optical rotation measurements.
