A convergent synthesis of four stereoisomers of the sex pheromone of the western corn rootworm (8-methyldecan-2-yl propionate, 1) from commercially available chiral starting materials is reported. The key step was Julia–Kocienski olefination between chiral BT-sulfone and chiral aldehyde. This synthetic route provided the four stereoisomers of 1 in 24–29% total yield via a six-step sequence. The simple
报道了从市售手性起始材料合成西部玉米根虫性信息素的四种立体异构体(8-methyldecan-2-yl propionate, 1)。关键步骤是手性 BT-砜和手性醛之间的 Julia-Kocienski 烯化。该合成路线通过六步序列以 24-29% 的总产率提供了 1 的四种立体异构体。简单的放大策略为实现性信息素的不对称合成提供了一种新方法。
