Unnatural aromatic amino acids are useful tools in drug discovery, since their insertion in bioactive peptide sequences can change the side chains spatial orientation, the backbone conformation and above all, their bioactivity. In this communication, we propose a straightforward method to synthesize 2′,6′‐dimethyl‐tyrosine and 2′,6′‐dimehylphenyl‐alanine derivatives as handling building blocks for
非天然芳族氨基酸是药物发现中的有用工具,因为它们插入生物活性肽序列中可以改变侧链的空间方向,主链构象以及最重要的是其生物活性。在本文中,我们提出了一种简单的方法来合成2',6'-二甲基酪氨酸和2',6'-二甲基苯基丙氨酸衍生物,作为通过不饱和二酮哌嗪(DKP)中间体进行肽合成的基础。
