  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。

  The enantiomers of 21-methyl-7-hentriacontanone (1), which might show weak bioactivity as the female sex pheromone of the screwworm fly (Cochliomyia hominivorax), were synthesized by starting from the enantiomers of citronellal. (±)-Citronellol was converted to a racemic and diastereomeric mixture of 5-acetoxy-19-methylnonacosane (2), which was considered to be a candidate for the female sex pheromone of C. hominivorax. Synthetic 2 exhibited no pheromone activity against male C. hominivorax.

  以香茅醛的对映体为起点，合成了 21-甲基-7-hentriacontanone（1）的对映体，该对映体作为螺蝇（Cochliomyia hominivorax）的雌性信息素可能显示出微弱的生物活性。(±)-香茅醛被转化为 5-乙酰氧基-19-甲基壬烷（2）的外消旋非对映异构体混合物，被认为是 C. hominivorax 雌性信息素的候选物质。合成物 2 对雄性 C. hominivorax 没有信息素活性。
