摘要:
The naturally occurring gamma-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. (C) 2002 Elsevier Science Ltd. All rights reserved.
