Outline of Final Research Achievements

A novel strategy for asymmetric photochemistry has been developed utilizing charge transfer interaction as the one of the weak intra- and intermolecular interactions. With a guidance by Prof. Thorsten Bach and his research group, chiral Lewis acid-mediated photoreaction was more critically investigated in view of physical chemistry perspective, realizing the novel strategy to control the stereochemistry of photoreactions. Nearly 40 scientific papers have been published as an outcome. Moreover, this project allowed to develop a significant international network, which means a lot in the future collaborations.

Academic Significance and Societal Importance of the Research Achievements

熱反応による不斉合成反応は医薬品合成などにおいて欠かせない変換反応となっている。光を用いる合成は、光エネルギーを直接生成物のエネルギーに変換可能であるため、高ひずみ化合物などの特異な構造形成に有利であり、しばしば天然物合成に用いられて生きた。しかしながら不斉合成の観点からはまだ成熟していない。本研究は、そのような溝を埋めるため、弱い相互作用を活用することで不斉光反応の立体選択性を制御する方法論を実証するものである。複雑な医薬品合成に新しいパラダイムを提供できるものと考えている。
