黑腹尼虎天牛是一种危害林木与果树的蛀干害虫, 其接触性信息素为(R)-9-甲基二十七烷、(R)-7-甲基二十五烷和(R)-7-甲基二十七烷. 以(S)-环氧丙烷为手性源, 环氧丙烷与格氏试剂的开环加成、仲磺酸酯与格氏试剂的SN2烷基化以及手性醛的Wittig偶联为关键步骤, 发展了一种新的合成黑腹尼虎天牛接触性信息素的方法.

关键词: 黑腹尼虎天牛, 接触性信息素, 手性源, (S)-环氧丙烷, 不对称合成

Neoclytus acuminatus acuminatus (Fabricius) is a wood-boring pest of forests and orchards. Its contact sex pheromones were (R)-9-methylheptacosane, (R)-7-methylheptacosane and (R)-7-methylpentacosane. A new and efficient synthesis of the contact sex pheromone was developed from chiral synthon of (S)-2-methyloxirane. This procedure mainly involved ring-opening reaction of (S)-2-methyloxirane, SN2 allylation of secondary tosylate and Wittig coupling of chiral aldehyde.

Key words: Neoclytus acuminatus acuminatus, contact sex pheromone, chiral source, (S)-2-methyloxirane, asymmetric synthesis
