[反应:见正文] 在未受保护的官能团存在下选择性形成酰胺键是肽化学的一个具有挑战性的问题。当在温和的水性条件下添加肽硫酯时,观察到束缚在模型肽 N 末端的 2-巯基苄基有利于酰胺键的形成。
[reaction: see text] The selective formation of an amide bond in the presence of unprotected functional groups is a challenging problem of peptide chemistry. A 2-mercaptobenzyl group tethered at the N-terminus of model peptides was observed to facilitate amide bond formation when a peptide thioester was added under mild aqueous conditions.
