Abstract

A protected tripeptide Boc-l-Leu-5-AIA-Aib-OMe was synthesized where 5-aminoisophthalic acid (5-AIA), a rigid non-coded aromatic γ-amino acid is incorporated as central residue. The single crystal X-ray diffraction study indicates that the peptide self-assembles into supramolecular sheet through intermolecular hydrogen bonding interaction N–H⋯O and π ··· π interaction.

包含中心位置非编码芳香族γ-氨基酸的三肽的合成与晶体结构
研究人员合成了一种受保护的三肽 Boc-l-Leu-5-AIA-Aib-Ome,其中 5-氨基间苯二甲酸(5-AIA)是一种刚性的非编码芳香族γ-氨基酸,作为中心残基。单晶 X 射线衍射研究表明,多肽通过分子间氢键作用 N-H⋯O 和 π -- π 相互作用自组装成超分子片。
