Outline of Final Research Achievements |
Catalytic reactions that convert stable and readily available organic molecules into key intermediates for pharmaceuticals and agrochemicals under mild conditions are expected to revolutionize synthetic processes in terms of reducing the number of steps and waste by-products. To realize such catalytic reactions, we proposed the concept of hybrid catalysis, which utilizes the function of multiple catalysts in a concerted and integrated manner. Based on this concept, we have found reactions that activate stable and readily available organic molecules such as simple alkenes, alcohols, and carboxylic acids, and transform them into useful chiral molecules via highly stereoselective carbon frame construction. We have also found reactions that convert alcohols to ketones while releasing molecular hydrogen.

Academic Significance and Societal Importance of the Research Achievements |
複数の触媒を重奏的に用いることで、従来法では用いることのできなかった化学的に安定な原料を精密有機合成の範疇に取り込み、医農薬の合成中間体を単工程で廃棄物を低減しながら合成できるようになった。そのために、設計・制御した電子移動を用いたり、機械学習の支援により複数の不斉触媒のキラリティをマッチングしたり、といった新規な学術手法を開発・発展させたところに意義がある。このようなハイブリッド触媒系の創製を通じて、有用物質の効率的生産や有機分子を水素キャリアとして用いるための化学的基盤の端緒を拓いた点に社会的意義がある。
