There are provided methods of efficiently producing compounds that are, for example, sex pheromones of San Jose Scale. For example, there is provided a method for producing a 7-methyl-3-methylene-7-octenyl carboxylate compound (4), the method including the steps of: hydrolyzing a 7-methyl-3-methylene-7-octenal acetal compound (1) to obtain 7-methyl-3-methylene-7-octenal (2); reducing the 7-methyl-3-methylene-7-octenal (2) to obtain 7-methyl-3-methylene-7-octenol (3); and esterifying the 7-methyl-3-methylene-7-octenol (3) to obtain a 7-methyl-3-methylene-7-octenyl carboxylate compound (4).
本发明提供了高效生产圣何塞鳞片性信息素等化合物的方法。例如,提供了一种生产 7-甲基-3-亚甲基-7-辛烯羧酸酯化合物(4)的方法,该方法包括以下步骤:水解 7-甲基-3-亚甲基-7-辛烯醛缩醛化合物 (1),得到 7-甲基-3-亚甲基-7-辛烯醛 (2);还原 7-甲基-3-亚甲基-7-辛烯醛 (2),得到 7-甲基-3-亚甲基-7-辛烯醇 (3);以及酯化 7-甲基-3-亚甲基-7-辛烯醇 (3),得到 7-甲基-3-亚甲基-7-辛烯羧酸酯化合物 (4)。
