    Pheromone chirality of african palm weevil,Rhynchophorus phoenicis (F.) and palmetto weevil,Rhynchophorus cruentatus (F.) (Coleoptera: Curculionidae)
    摘要:
    There are four stereoisomers of both 3-methyl-octan-4-ol, the aggregation pheromone of the African palm weevil, Rhynchophorus phoenicis (F.) and 5-methyl-octan-4-ol, the aggregation pheromone of the palmetto weevil, Rhynchophorus cruentatus (F.). Synthetic stereoisomers of 3-methyl-octan-4-ol and 5-methyl-octan-4-ol were baseline-separated on a Cyclodex-B fused silica column. Use of this column in gas chromatographic-electroantennographic detection (GC-EAD) and GC-mass spectrometric (GC-MS) analyses revealed that only one stereoisomer, (3S,4S)-3-methyl-octan-4-ol and (4S,5S)-5-methyl-octan-4-ol, is produced by male R. phoenicis and male R. cruentatus, respectively, and elicits good antennal responses by conspecific male and female weevils. In field trapping experiments, with R. phoenicis in Cote d'Ivoire and R. cruentatus in Florida, (3S,4S)-3-methyl-octan-4-ol and (4S,SS)-5-methyl-octan-4-ol strongly enhanced attraction of fresh palm tissue, whereas other stereoisomers were behaviorally benign. Stereoisomeric 3-methyl-octan-4-ol and 5-methyl-octan-4-ol may be utilized to monitor and/or manage populations of these two palm weevils.

    Shape selective oxidation using titanium silicates: epoxidation of dihydromyrcene and the model compounds 2-methylpent-2-ene and 3-methylpent-1-ene
    摘要:
    二氢美克烯的选择性环氧化在含钛的硅酸盐TS-1和TiAlβ的存在下进行了研究,使用的氧化剂包括水合过氧化氢、叔丁基过氧化氢和尿素-过氧化氢复合物。在TS-1和水合过氧化氢的体系中观察到了环氧化物,在TiAlβ的体系中则需与尿素-过氧化氢复合物和叔丁基过氧化氢共同使用。环氧化反应仅在更富电子的双键上进行,在两种催化剂的存在下均为如此。二氢美克烯的环氧化反应还在三相条件下(两个不混溶的液相和一个催化剂相)进行了研究,而非在两相条件下(一个液相和一个催化剂相)。结果发现,在两相条件下生成的环氧化物的醇解反应通过更稳定的阳离子中间体进行。相比之下,在三相条件下的醇解反应则同时形成了主要( favored)和次要(unfavored)的醚醇,其比例可达2:1。为了研究每个双键的环氧化程度,使用了模拟二氢美克烯中每个双键周围电子环境的模型化合物(2-甲基戊-2-烯和3-甲基戊-1-烯),在竞争条件下分别进行了单独研究。当单独研究这些模型底物时,两个双键的环氧化速率相当。然而,在竞争性环氧化中,电子不足的双键优先被氧化,这与二氢美克烯的观察结果有所不同。
