  Synthesis of All the Stereoisomers of 10,14‐Dimethyloctadec‐1‐ene, 5,9‐Dimethyloctadecane and 5,9‐Dimethylheptadecane, the Sex Pheromone Components of the Apple Leafminer, Lyonetia prunifoliella

  摘要：

  All of the stereoisomers of 10,14-dimethyloctadec-1-ene (1), 5,9-dimethyloctadecane (2) and 5,9-dimethylheptadecane (3), the sex pheromone components of the apple leafminer (Lyonetia prunifoliella), were synthesized by starting from the enantiomers of citronellol (4) and methyl 3-hydroxy-2-methylpropanoate (11).

  Lyonetia prunifoliella is a significant pest in orchards and damages apple. The sex pheromones of this pest were prepared via a new and concise method. The central to our method were Evans' chiral auxiliaries, the addition of chiral Grignard reagent to aldehyde and Wittig coupling.

  Lyonetia prunifoliell a 是果园的重要害虫，为害苹果。这种害虫的性信息素是通过一种新的、简洁的方法制备的。我们方法的核心是 Evans 的手性助剂，将手性格氏试剂添加到醛和 Wittig 偶联中。

  Both (2R,6R)- and (2S,6S)-isomers of 2,6-dimethylheptane-1,7-diol monotetrahydropyranyl ether (4) were synthesized, and converted into the enantiomers of anti-10,14-dimethyl-1-octadecene (1), anti-5,9-dimethyloctadecane (2) and anti-5,9-dimethylheptadecane (3), the sex pheromone components of the apple leaf miner (Lyonetia prunifoliella).
