  摘要：

  The sex pheromone of the citrus fruit borer Ecdytolopha aurantiana has been identified by gas chromatography coupled to an electroantennographic detector (GC-EAD). The electron impact mass spectral (EI-MS) fragmentation of the major EAD-active peak gave identifying features for a monounsaturated acetate. Further analyses by chemical ionization mass spectrometry (CI-MS), vapor-phase infrared spectroscopy (GC-IR), along with chemical derivatization (DMDS reaction), led to full characterization of the major component as (E)-8-dodecenyl acetate (E8-12: Ac). The second constituent was identified as the related alcohol, (E)-8-dodecenol (E8-12: OH). The;two compounds were indistinguishable from the authentic synthetic standards in chemical and EAD analyses. Samples of the two compounds were obtained by a facile synthesis utilizing lithium chemistry. Field tests showed that captures in traps baited with a mixture of E8-12: Ac and E8-12: OH at 100: 1 and 10: 1 ratios were not significantly different from the catches in traps having two virgin females, Dosage tests showed better performance of traps baited with I mg than those with 0.1 mg of the pheromone blend, either in 100: 1 or 10: 1 ratio.

  日期：——

  (Z)-Alkenols and Their acetates have been synthesized by the Wittig reaction of (ω-hydroxyalkyl)triphenylphosphonium salts with alkanals by a convenient procedure. The geometrical purity of the products was evaluated to be no less than 95% of the (Z)-configu-ration by means of GLC with a glass capillary column coated with CHDMS.

  通过一种简便的方法，利用Wittig反应将（ω-羟基烷基）三苯基膦盐与烷基醛反应，合成了（Z）-烯醇及其乙酸酯。通过涂有CHDMS的玻璃毛细管柱进行GC分析，评估产物的几何纯度不小于95%的（Z）构型。

  In one aspect, the invention provides a method for synthesizing a fatty olefin derivative. The method includes: a) contacting an olefin according to Formula I with a metathesis reaction partner according to Formula IIb in the presence of a metathesis catalyst under conditions sufficient to form a metathesis product according to Formula IIIb: and b) converting the metathesis product to the fatty olefin derivative. Each R 1 is independently selected from H, C 1-18 alkyl, and C 2-18 alkenyl; R 2b is C 1-8 alkyl; subscript y is an integer ranging from 0 to 17; and subscript z is an integer ranging from 0 to 17. In certain embodiments, the metathesis catalyst is a tungsten catalyst or a molybdenum catalyst. In various embodiments, the fatty olefin derivative is a pheromone. Pheromone compositions and methods of using them are also described.

  In certain aspects, the present invention provides methods for producing terminally hydroxylated alkenes and alkynes by contacting an unsaturated or saturated hydrocarbon substrate with a hydroxylase enzyme. Exemplary terminal hydroxylases useful for carrying out the methods of the invention exhibit strong selectivity towards one terminal carbon of a hydrocarbon substrate and include, but are not limited to, non-heme diiron alkane monooxygenases, cytochromes P450 (e.g., cytochromes P450 of the CYP52 and CYP153 family), as well as long chain alkane hydroxylases. In some embodiments, the terminally hydroxylated alkene or alkyne is further converted to a terminal alkenal. In certain embodiments, terminally hydroxylated alkenes and alkynes are useful as insect pheromones which modify insect behavior. In other embodiments, terminally hydroxylated alkenes and alkynes are useful intermediates for producing pheromones via acetylation or oxidation of the alcohol moiety.

  在某些方面，本发明提供了一种通过将不饱和或饱和碳氢基质与羟化酶酶接触来生产末端羟基化烯烃和炔烃的方法。用于执行本发明方法的示例末端羟化酶对碳氢基质的一个末端碳具有很强的选择性，包括但不限于非血红素双铁脂烷单氧酶、细胞色素P450（例如，CYP52和CYP153家族的细胞色素P450）以及长链烷烃羟化酶。在某些实施例中，末端羟基化的烯烃或炔烃进一步转化为末端烯醛。在某些实施例中，末端羟基化的烯烃和炔烃可用作改变昆虫行为的昆虫信息素。在其他实施例中，末端羟基化的烯烃和炔烃是通过乙酰化或氧化醇基团来生产信息素的有用中间体。
