The present strategy provides ways to introduce functionalities such as N-acyloxyphthalimide or -succinimide specifically to terminal glycine segment of peptides. Herein, mild conditions and high functional-group tolerance allow the preparation of non-natural α-amino acids and modification of corresponding peptides in this way.
甘
氨酸和肽的室温、可见光促进和氧化还原中性直接 C-H 胺化首先通过使用N-酰氧基邻苯二甲
酰亚胺或 -琥珀
酰亚胺作为氮自由基前体来实现。本策略提供了将诸如N-酰氧基邻苯二甲
酰亚胺或-琥珀
酰亚胺之类的官能团特异性引入肽的末端甘
氨酸片段的方法。在此,温和的条件和高官能团耐受性允许以这种方式制备非天然
α-氨基酸和相应肽的修饰。
