(E)-ISOPROPYL-5-METHYL-3,5-HEXADIENOATE COMPOUND, METHOD FOR PRODUCING THE SAME, AND METHODS FOR PRODUCING (E)-2-ISOPROPYL-5-METHYL-3,5-HEXADIENOL AND (E)-2-ISOPROPYL-5-METHYL-3,5-HEXADIENYL CARBOXYLATE BY USING THE SAME

摘要

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).
