METHOD FOR PRODUCING 2-ISOPROPENYL-5-METHYL-4-HEXEN-1-YL 3-METHYL-2-BUTENOATE |
摘要 |
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).; |
