| Outline of Final Research Achievements |
Synthesis of α,α-disubstituted α-amino acids and their peptides were performed. Secondary structural analysis of these peptides could be useful for design of peptide foldamers. α-Trifluoromethylated α,α-disubstituted α-amino acids were synthesized with a variety of side chains. Optical resolution of these amino acids were achieved by chromatographic separation of the corresponding (R)-BINOL ester derivative. We also synthesized α-amino acids possessing rare sugar on their side chain. Simplification of peptide catalyst structure resulted in high catalytic activity, which is important from the point of green sustainability.

| Academic Significance and Societal Importance of the Research Achievements |
生体内で重要な役割を担うペプチドは、機能性分子としての高いポテンシャルを有している。今回フッ素を導入したペプチドにより、バイオアベイラビリティーの増大が期待でき、また一方で、希少糖を導入したアミノ酸を今後ペプチドへ導入していくことで、生体内リガンドとしての可能性も高まる。ペプチド触媒の簡素化による触媒活性の向上は、化合物のロスを減らし、グリーンサスティナビリティの向上に資する結果と考えられる。
