Methyl (,,)-2,4,6-decatrienoate () is the aggregation pheromone of the brown-winged green bug, and is also a pheromone synergist of the brown marmorated stink bug, pheromone. A scalable and controllable synthesis of methyl (,,)-2,4,6-decatrienoate () was achieved in 5 steps. The stereoselective formation of the 4, 6 conjugated double bond was accomplished by a tandem addition reaction of acrolein with
(,,)-2,4,6-十碳三烯酸甲酯()是褐翅绿蝽的聚集信息素,也是褐斑蝽信息素的信息素增效剂。通过 5 个步骤实现了 (,,)-2,4,6-十碳三烯酸甲酯 () 的可扩展和可控合成。 4、6共轭双键的立体选择性形成是通过丙烯醛与乙炔的串联加成反应完成的,2双键是通过Heck反应形成的。从 (,)-7-溴-4,6-庚二烯醛开始,获得了 99% 立体化学纯度和 40% 总产率的信息素。
