The naturally occurring γ-cyclogeranylgeraniol called (+)-trixagol has been synthesised for the first time. Trixagol was readily available in five steps from ( S )-2,2-dimethyl-6-methylene-1-cyclohexanemethanol. The enantiomer of trixagol, which equates to the terpenoid side chain of the naturally occurring 7,9-dialkylpurinium salt (−)-agelasine E, was prepared from the ( R ) enantiomer of the cyclohexanemethanol. Both trixagol enantiomers were moderately active against Mycobacterium tuberculosis . |
