Outline of Annual Research Achievements

前年度に発見された、ホウ素によるアルコール認識を介したC(sp3)-H変換の開発に取り組んだ。すなわち、ボレート型認識によりアルコールα位C-H結合の弱化現象が観測され、反応促進に関与するとともに、位置選択的なC(sp3)-H結合編案に繋がるものと考えられた。可視光レドックス触媒(PC)-水素原子移動触媒(HAT)系とホウ素結合弱化触媒系を共同させる形でアルコールα位およびMichaelアクセプターを結合させるC-Hアルキル化系を開発し、原著論文として報告できた(Synthesis, in press)。
また並行して、より酸化耐性のあるケイ素化合物をホウ素の代わりに活用可能である事実も見いだすことができた。同様の反応形式にてシリカート型結合弱化現象を実証し、こちらも原著論文として報告した(Adv. Synth. Catal. 362, 337)。
これらはラジカル共役型錯体触媒系と協働させることにより、従来型触媒系では実現不可能なアルコール原料の新反応形式への拡張にあたって、基盤となる発見と言える。
