All eight geometric isomers of methyl 2,4,6-decatrienoate were synthesized from readily accessible starting materials by fully exploiting Wittig-type olefinations, and taking advantage of an easy separation of 2E and 2Z unsaturated esters. The aggregation pheromone of the brown-winged green bug, Plautia stali, methyl (E,E,Z)-2,4,6-decatrienoate (also a cross-attractant for the brown marmorated stink
通过充分利用维蒂希型烯烃,并容易分离2 E和2 Z不饱和酯,从易于获得的原料合成了2,4,6-癸三烯酸甲酯的所有8种几何异构体。棕色翅绿色臭虫,所述的聚集信息素Plautia stali,甲基(ê,ê,Ž)-2,4,6- decatrienoate(也横引诱的九香虫,茶翅蝽),这是有利(E)-4,4-二甲氧基-2-丁烯醛通过两个简单的步骤制备,收率为55%。红肩臭臭虫Thyanta pallidovirens的性信息素(甲基E,Z,Z)-2,4,6-癸二烯酸酯,可以方便地由2,4-辛二炔-1-醇以32%的收率使用原位二氧化锰氧化-关键步骤Wittig缩合合成。
