  摘要：

  The methanolic extract obtained from rose flowers was subjected to XAD-8 adsorption chromatography. Prefractionation of the methanolic eluate using multilayer coil countercurrent chromatography (MLCCC) yielded five subfractions. From the least polar subfraction V, a major amount of the key odorants of rose oil, that is, isomeric rose oxides 1a/b, was liberated upon heat treatment at pH 2.5. Further chromatographic workup of fraction V led, for the first time, to the identification of the genuine rose oxide precursor (S)-3,7-dimethyl-5-octene-1,7-diol (2). In addition to diol 2, the following monoterpene diols have been identified: 3,7-dimethyl-7-octene-1,6-diol (3), 2,6-dimethyl-1,7-octadiene-3,6-diol (4), (2E,5E)-3,7-dimethyl-2,5-octadiene-1,7-diol (5), (2E)-3,7-dimethyl-2,7octadiene-1,6-diol (6), (2Z,5E)-3,7-dimethyl-2,5-octadiene-1,7-diol (7), (2Z)-3,7-dimethyl-2,7-octadiene-1,6-diol (8), (Z)-2,6-dimethyl-2-octene-1,8-diol (9), (E)-2,6-dimethyl-2-octene-1,8-diol(10), (2)-2,6-dimethyl-2,7-octadiene-1 ,6-diol(ll), (E)-2,6-dimethyl-2,7-octadiene-1,6-diol (12), (2E,GE)-2,6-dimethyl-2 ,6-octadiene-1,8-diol(13), (2E,6Z)-2,6-dimethyl-2,6-octadiene-1,8-diol(14), 2,6-dimethyloctane-1,8-diol(15), 2,6-dimethyl-7-octene-1,6-diol (16), (E)-3,7-dimethyl-2-octene-1,8-diol (17), (Z)-3,7-dimethyl-2-octene-1,8-diol (18), 3,7-dimethyloctane-1,7-diol (19), 2,6-dimethyl-7-octene-2,6-diol (20), 3,7-dimethyl-6-octene-1,3-diol (21) and (2E)-3,7-dimethyl-2,6-octadiene-1,4-diol (22).

  香叶醇，尼尔及其合成的氧化衍生物的结构-气味关系研究

  摘要：

  尽管是具有相同柑橘样花香气味的异构体，但香叶醇1和香叶醇3却显示出不同的气味阈值。迄今为止，尚无系统的研究来阐明其特定气味特性所需的结构特征。因此，从这两个基本结构及其相应的酯（即乙酸香叶酯2和乙酸神经酯4）开始，合成了总共12种含氧化合物，并对其保留指数（RI），质谱（MS）和核磁共振（NMR）数据。分别测试了所有化合物的气味质量和空气中的气味阈值（OT）。香叶醇Z发现OT值为14 ng / L的α-异构体比其OT为60 ng / L的E-异构体nerol更有效。但是，乙酸8-氧杂戊酯是这项研究中最有效的衍生物，OT值为8.8 ng / L，而8-氧合己内酯的效力最差，OT为493 ng / L。有趣的是，8-氧代衍生物闻起来有霉味和脂肪，而8-羟基衍生物则显示出与1和3相似的气味。发现8-羧基香叶醇无味，而其E-异构体8-羧基神经醇显示出脂肪，蜡状和油腻感。总体而言，我们观察到C-8上的氧化主要影响气味质量，而E

• The aphid sex pheromone cyclopentanoids: Synthesis in the elucidation of structure and biosynthetic pathways

  Identification of a range of aphid sex pheromones as comprising the cyclopentanoids (4aS,7S,7aR)-nepetalactune, (1R,4aS,7S,7aR)-nepetalactol and the (1S)- and (1R,4aR,7S,7aS)-nepetalactols required samples authenticated by H-1 and C-13 NMR. These and related compounds were provided by small scale synthesis and extraction from plants in the genus Nepeta (Lamiaceae). The subsequent discovery that the synthetic sex pheromones could attract males, and also parasitic wasps that attack aphids, has created a need for large scale syntheses of the cyclopentanoids. This is afforded by cyclisation of the 8-oxo-1-enamine of citronellal as originally developed by Schreiber and co-workers (1986). Investigation into the biosynthesis of the cyclopentanoids by plants for exploiting aphid sex pheromones in crop protection by means of molecular biology required synthesis of putative biosynthetic intermediates, some with radioactive isotopic labelling, particularly 8-oxidised monoterpene alcohols and aldehydes.
