title: Enantioselective Total Syntheses of (-)-7betaH-Eudesmane-4alpha,11-diol and (+)-ent-7betaH-Eudesmane-4alpha,11-diol
abstract: The syntheses of (-)-7betaH-eudesmane-4alpha,11-diol (2) and (+)-ent-7betaH-eudesmane-4alpha,11-diol (ent-2) were carried out starting from (-)- and (+)-dihydrocarvones. As a result, the structure, including absolute configuration, of the naturally occurring eudesmane-4,11-diol isolated from Pluchea arguta was determined to be (+)-ent-7betaH-eudesmane-4alpha,11-diol (ent-2).
