    摘要: Provided are methods including a method for industrially producing (2S,12Z)-2-acetoxy-12-heptadecene, which is, for example, a sex pheromone of pistachio twig borer. The methods can include a production method comprising a step of reacting racemic (2RS,12Z)-2-hydroxy-12-heptadecene with vinyl benzoate in the presence of a lipase to obtain a mixture of optically active (2R,12Z)-2-benzoyloxy-12-heptadecene of Formula (R,Z-2) and optically active (2S,12Z)-2-hydroxy-12-heptadecene of Formula (S,Z-1), a step of heating the mixture to distill out the optically active (2S,12Z)-2-hydroxy-12-heptadecene (S,Z-1), and a step of acetylating the optically active (2S,12Z)-2-hydroxy-12-heptadecene (S,Z-1) to obtain optically active (2S,12Z)-2-acetoxy-12-heptadecene of Formula (S,Z-3).

    摘要: Provided is a simple and efficient method for producing (E)-2-isopropyl-5-methyl-2,4-hexadienyl acetate. More specifically, provided is a method for producing (E)-2-isopropyl-5-methyl-2,4-hexadienyl acetate including the steps of: isomerizing 2-isopropenyl-5-methyl-4-hexenoic acid (1) into (E)-2-isopropyl-5-methyl-2,4-hexadienoic acid (2), reducing thus formed (E)-2-isopropyl-5-methyl-2,4-hexadienoic acid (2) into (E)-2-isopropyl-5-methyl-2,4-hexadienol (3), and acetylating thus formed (E)-2-isopropyl-5-methyl-2,4-hexadienol (3) into (E)-2-isopropyl-5-methyl-2,4-hexadienyl acetate (4), wherein Ac represents an acetyl group.
