Document Type and Number:
Japanese Patent JP6553553
Kind Code:
B2
Abstract:
Provided are industrial and economical methods for producing 2,6-dimethyl-1,5-heptadien-3-yl acetate (3), which is, for example, a sex pheromone component of Comstock mealybug, and 2,6-dimethyl-1,5-heptadien-3-ol (2), which is an intermediate of the acetate (3). More specifically, provided are a method for producing 2,6-dimethyl-1,5-heptadien-3-ol comprising a step of subjecting 2-methyl-3-buten-2-yl 2-methyl-2-propenyl ether (1) to a rearrangement reaction in the presence of a base to obtain 2,6-dimethyl-1,5-heptadien-3-ol (2), and a method for producing 2,6-dimethyl-1,5-heptadien-3-yl acetate comprising a step of acetylating the produced 2,6-dimethyl-1,5-heptadien-3-ol (2) to obtain 2,6-dimethyl-1,5-heptadien-3-yl acetate (3).
