  Natural and Unnatural Terpenoid Precursors of Insect Juvenile Hormone

  摘要：

  The biosynthesis of insect juvenile hormone (JH) is due, in part, to the precise head-to-tail coupling of allylic and homoallylic diphosphate substrates, as catalyzed by one or more prenyltransferases. To better understand this enzyme's role in JH production, homodimethylallyl diphosphate and both the natural and unnatural homologs of geranyl diphosphate have been prepared as potential substrates for insect prenyltransferase. These latter materials were constructed in a convergent manner by olefination of the corresponding trisnoraldehydes obtained from either terminal oxidative cleavage of geraniol or higher-order cuprate conjugate addition to acrolein. To aid in characterizing the nature of the terpenoid skeletons formed from our in vitro studies, homologous derivatives of farnesol were also prepared by anion coupling of the geranyl derivatives to either C-5 or C-6 allylic bromides. The preparation of these materials and the results of incubations with larval corpora allata homogenates of the lepidopteran Manduca sexta are described.
