  摘要：

  Agelasine E以前是从海洋海绵Agelas nakamurai中分离出来的，它是与具有各种萜类侧链的类似物一起首次合成的。用烯丙基溴处理N6-甲氧基-9-甲基-9H-嘌呤-6-胺，得到所需的7,9-二烷基pur盐以及少量的N6-烷基化异构体。最后，N6-甲氧基被还原性除去。1H-15N HMBC和1H-15N HSQC NMR光谱学提供了有关所研究的嘌呤衍生物中互变异构和电荷离域的其他信息。筛选了杂环产物对结核分枝杆菌的活性，在嘌呤7-位带有相对较长的萜类取代基和N-6处的甲氧基基团的长老苷类似物是有效的细菌生长抑制剂。

  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 agelasine analogs 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 agelasine analogs with the geranylgeranyl chain at N-7 exhibited antimicrobial activity, several strategies
