Outline of Final Research Achievements

We have developed a silyl-group-directed β-selective C-H functionalization reaction of organosilicon compounds without coordinating directing groups. Dirhodium-catalyzed C-H amination takes place effectively to provide β-aminosilanes from simple organosilanes. Mechanistic analysis based on experiment and calculation revealed that β effect of silicon atoms is responsible for the site selectivity. The present method was applied to catalytic asymmetric reaction with chiral dirhodium complexes to give a β-aminated product in good optical purity.

Academic Significance and Societal Importance of the Research Achievements

有機化合物に普遍的に存在するC-H結合を直接望みの結合に変換する手法の開発は、合成工程を革新する可能性から盛んに研究が行われている。本研究ではシリル基のβ効果に着目し、これまで報告例のないβ位選択的C-Hアミノ化法を開発することができた。本法は有用なビルディングブロックであるアミノシラン類を単純な有機ケイ素化合物から効率的に合成できる手法として価値が高く、不斉反応への展開も可能であることから、ファイケミカルの効率的合成への展開が期待される。
