Abstract

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).
