Provided is a method for industrially producing 2-isopropenyl-5-methyl-4-hexen-1-yl 3-methyl-2-butenoate, which is, for example, a sex pheromone substance of vine mealybug. More specifically, there is provided a method for producing 2-isopropenyl-5-methyl-4-hexen-1-yl 3-methyl-2-butenoate, comprising a step of transesterifying 2-isopropenyl-5-methyl-4-hexen-1-ol represented by Formula (1) with alkyl senecioate represented by General Formula (2) in the presence of a catalyst, while distilling off an alcohol represented by General Formula (4) formed as a by-product, to obtain 2-isopropenyl-5-methyl-4-hexen-1-yl 3-methyl-2-butenoate represented by Formula (3).
提供了一种用于工业生产2-异丙烯基-5-甲基-4-己烯-1-基 3-甲基-2-丁烯酸酯的方法,该物质例如是葡萄藤粉虱的性信息素。更具体地,提供了一种生产2-异丙烯基-5-甲基-4-己烯-1-基 3-甲基-2-丁烯酸酯的方法,包括在催化剂存在下,通过将通式(1)表示的2-异丙烯基-5-甲基-4-己烯-1-醇与通式(2)表示的烷基塞内酸酯进行酯交换反应的步骤,同时蒸馏掉作为副产物形成的通式(4)表示的醇,以获得通式(3)表示的2-异丙烯基-5-甲基-4-己烯-1-基 3-甲基-2-丁烯酸酯。
