不同杂环取代(E)-β-Farnesene类似物的合成及生物活性研究

Synthesis and Biological Activity of Different Heterocyclic Substituted(E)-β-Farnesene Analogues

为了寻求新型蚜虫控制剂,以蚜虫报警信息素(E)-β-farnesene(EBF)为先导,引入不同类型的杂环取代EBF结构中不稳定的共轭双键,设计合成了一系列不同杂环取代的EBF类似物.所有化合物结构均通过1H NMR、13C NMR、IR及HRMS确证.对化合物进行了生物活性测试及初步构效关系分析.结果表明,所有化合物均对桃蚜和大豆蚜表现出一定的生物活性,部分化合物的杀虫活性优于先导EBF,酯基的引入则对驱避活性有利.

In order to discover novel aphid control agent, aphid alarm pheromone（E）-β-farnesene（EBF） was chosen as lead compound and a series of substituted EBF analogues were designed by replacing unstable conjugated double bond of EBF with different kinds of heterocyclic rings. All the compounds were synthesized and their structures were confirmed by 1H NMR, 13 C NMR, IR spectra and HRMS analysis. Biological test showed that all the compounds displayed insecticidal or repellency activity to Myzuspersicae（Sulzer） or Aphis glycines（Matsumura）. Some of them exhibited higher insecticidal activity than EBF. Introducing ester group was favorable to repellent activity.
