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).
提供的方法包括一种用于工业生产(2S,12Z)-2-乙酰氧基-12-庚烯的方法,例如,这是开心果枝小蠹的性信息素。该方法可以包括一个生产方法,其中包括以下步骤:在脂肪酶存在下,将外消旋(2RS,12Z)-2-羟基-12-庚烯与苯乙烯酸乙酯反应,以获得光学活性的(2R,12Z)-2-苯甲酰氧基-12-庚烯混合物(式(R,Z-2))和光学活性的(2S,12Z)-2-羟基-12-庚烯(式(S,Z-1)),加热混合物以蒸馏出光学活性的(2S,12Z)-2-羟基-12-庚烯(S,Z-1),乙酰化光学活性的(2S,12Z)-2-羟基-12-庚烯(S,Z-1)以获得光学活性的(2S,12Z)-2-乙酰氧基-12-庚烯(式(S,Z-3))。
