おいて多くの問題がある。 For this reason, many researchers have been researching the synthesis of optically pure bean pheromone, but there are still various problems. For example, in the above scheme, a method using α-pinene for the asymmetric reduction from (1) to (2) has been proposed, but generally speaking, according to this method, a large amount of α-pinene is added to (1). Furthermore, when α-pinene and 9-borabicyclo[3.3.1]nonane are used as asymmetric reducing agents, the reaction takes several days. It takes. As described above, the conventional methods have many problems in terms of efficiency and cost.
