Provided is a simple and efficient method for producing 2-isopropylidene-5-methyl-4-hexenyl butyrate. More specifically, provided is a method for producing 2-isopropylidene-5-methyl-4-hexenyl butyrate, the method including the steps of: isomerizing 2-isopropenyl-5-methyl-4-hexenoic acid ester (1) into 2-isopropylidene-5-methyl-4-hexenoic acid ester (2), reducing thus formed 2-isopropylidene-5-methyl-4-hexenoic acid ester (2) into 2-isopropylidene-5-methyl-4-hexenol (3), and butyrylating thus formed 2-isopropylidene-5-methyl-4-hexenol (3) into 2-isopropylidene-5-methyl-4-hexenyl butyrate (4),
wherein R represents a C

hydrocarbon group.
提供了一种简单高效的生产2-异丙基亚甲基-5-甲基-4-己烯基丁酸丁酯的方法。具体来说,提供了一种生产2-异丙基亚甲基-5-甲基-4-己烯基丁酸丁酯的方法,包括以下步骤:将2-异丙烯基-5-甲基-4-己烯酸酯(1)异构化为2-异丙基亚甲基-5-甲基-4-己烯酸酯(2),将形成的2-异丙基亚甲基-5-甲基-4-己烯酸酯(2)还原为2-异丙基亚甲基-5-甲基-4-己烯醇(3),并将形成的2-异丙基亚甲基-5-甲基-4-己烯醇(3)丁酰化为2-异丙基亚甲基-5-甲基-4-己烯基丁酸丁酯(4),其中R代表一个碳链为C1-10的烃基。
