PROBLEM TO BE SOLVED: To provide a simple and efficient method for producing (E)-isopropyl-5-methyl-2,4-hexadienyl acetate. ! SOLUTION: There is provided a method for producing (E)-2-isopropyl-5-methyl-2,4-hexadienyl acetate which comprises: a step of isomerizing 2-isopropenyl-5-methyl-4-hexenoic acid (1) to obtain (E)-2-isopropyl-5-methyl-2,4-hexadienoic acid (2); a step of reducing the resulting (E)-2-isopropyl-5-methyl-2,4-hexadienoic acid (2) to obtain (E)-2-isopropyl-5-methyl-2,4-hexadienol (3); and a step of acetylating the resulting (E)-2-isopropyl-5-methyl-2,4-hexadienol (3) to obtain (E)-2-isopropyl-5-methyl-2,4-hexadienyl acetate (4). (In the formula, Ac represents an acetyl group.) ! COPYRIGHT: (C)2015,JPO&INPIT |
