Synthesis of (+)-trixagol and its enantiomer, the terpenoid side chain of (−)-agelasine E
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.

delocalization in the purine derivatives studied. The heterocyclic products were screened for activity against Mycobacterium tuberculosis and agelasineanalogs carrying a relatively long terpenoid substituent in the purine 7-position and a methoxy group at N-6 were potent inhibitors of bacterial growth. Since agelasineanalogs with the geranylgeranyl chain at N-7 exhibited antimicrobialactivity, several strategies
