title: Absolute configuration of (-)-2,6-dimethyl-10-(p-tolyl)-2,6(E)-undecadiene from Cistus monspeliensis.
abstract: (-)-2,6-Dimethyl-10-(p-tolyl)-2,6(E)-undecadiene (1) is a major constituent in the essential oil of Cistus monspeliensis, an aromatic shrub common in Mediterranian countries. 1 was isolated by column chromatography, subjected to ozonolyses, and the absolute configuration was determined by enantioselective gas chromatographic correlation with the ozonolysis product of the sesquiterpene hydrocarbon ar-curcumene with known absolute configuration.
