Outline of Research at the Start

触媒的アミド化反応において,二核ホウ素錯体が重要な中間体であること,2種類のボロン酸を組み合わせるとよい結果を与えることが報告されている。そこで,2つのホウ素を連結するリンカー部位,ボロン酸の検討,適切な疎水性空孔などを与えることによって,含水溶媒中もしくは水溶液中にてアミド化反応を行うことのできる触媒を探索する。

Outline of Final Research Achievements

In this study, we investigated the development of boronic acid catalysts that can give amides from various carboxylic acids and amines at room temperature for several hours without racemization, and that can be catalyzed in aqueous solution. Since dinuclear boron complexes were expected to be important intermediates in catalytic amidation reactions, we investigated dinuclear boron complexes bridging two boronic acid moieties. Unfortunately, we were unable to develop a catalyst that would facilitate the desired amidation reaction in aqueous solution because our research time was limited by coronavirus infection. However, although somewhat divergent from the original purpose of the study, valuable insights were gained from the development of amidation reactions in aqueous and alcohol solvents.

Academic Significance and Societal Importance of the Research Achievements

二核ホウ素錯体について,ふたつのボロン酸部位を有することから,その極性が高くなって有機溶媒への溶解性が減少し,また,ふたつのボロン酸部位から脱水反応が容易に進行して複数の化合物を与えることから,合成には更なる合成研究が必要であることが示唆された.また,水もしくはアルコール溶媒中で,カルボン酸を活性化した中間体の反応性について広く研究を行った結果,僅かな電子的および立体的要因により,加溶媒分解の様子が変わることが分かった.ボロン酸触媒においても,活性中間体を経ることが予想され,加水分解や加アルコール分解を抑制するために触媒分子における電子的および立体的要因の考察が必須であるという知見が得られた.
