An asymmetric synthesis of 14-methyl-1-octadecene, the sex pheromone of the peach leafminer moth, has been efficiently achieved. A key chiral intermediate, (R)−4-(benzyloxy)−3-methylbutanal, which has been developed as the resource chemical, can be obtained in large quantities from the steroid industry. 1,11-Undecanediol is selectively masked, and then converted into a phosphonium salt derivative, thereby effectively constructing a carbon skeleton. The target molecule is synthesized in 8 linear steps, with a 42% yield. The key characteristic of our synthesis lies in its chiral-pool strategy.

( S )-14-Methyl-1-Octadecene 的一种新的不对称合成，桃叶潜蛾的性信息素

桃潜叶蛾的性信息素 14-methyl-1-octadecene 的不对称合成已被有效实现。一种关键的手性中间体( R )-4-(苄氧基)-3-甲基丁醛已被开发为资源化学品，可以从类固醇工业中大量获得。1,11-十一烷二醇被选择性掩蔽，然后转化为鏻盐衍生物，从而有效构建碳骨架。目标分子以 8 个线性步骤合成，产率为 42%。我们合成的关键特征在于其手性池策略。
