Provided is a geometrically selective method for producing (±)-(E)-2-isopropyl-5-methyl-3,5-hexadienyl acetate, which is a sex pheromone of grape pineapple mealybug (GPMB). Specifically provided is a method for producing a an (E)-2-isopropyl-5-methyl-3,5-hexadienyl carboxylate compound (4), the method comprising the steps of: dehydrating a 3-hydroxy-2-isopropyl-5-methyl-4-hexenoate compound (1) to obtain an (E)-2-isopropyl-5-methyl-3,5-hexadienoate compound (2); reducing the alkoxycarbonyl group of the compound (2) to obtain (E)-2-isopropyl-5-methyl-3,5-hexadienol (3); and esterifying the compound (3) to obtain the compound (4).
本发明提供了一种生产(±)-(E)-2-异丙基-5-甲基-3,5-己二烯基醋酸酯的几何选择性方法,该醋酸酯是葡萄菠萝蚧(GPMB)的一种性信息素。具体提供了一种生产(E)-2-异丙基-5-甲基-3,5-己二烯基羧酸酯化合物(4)的方法,该方法包括以下步骤:使 3-羟基-2-异丙基-5-甲基-4-己烯酸酯化合物(1)脱水,得到(E)-2-异丙基-5-甲基-3,5-己二烯酸酯化合物(2);还原化合物(2)的烷氧羰基,得到(E)-2-异丙基-5-甲基-3,5-己二烯醇(3);酯化化合物(3),得到化合物(4)。
