novel method for the synthesis of N-linked glycopeptides using the sugar-assisted ligation strategy from cysteine free peptides is presented. The ligation junction tolerates a variety of amino acids, favoring less hindered amino acids and those with side chains that could serve as a general base in the ligation pathway. Since our approach allows the ligation of difficult junctions, the method could
提出了一种使用糖辅助连接策略从半胱氨酸游离肽合成 N 连接糖肽的新方法。连接点耐受多种氨基酸,有利于受阻较少的氨基酸和具有侧链的氨基酸,可作为连接途径中的一般碱基。由于我们的方法允许连接困难的连接,该方法可用于通过酶促去除糖部分来合成大肽。或者,可以使用糖基转移酶合成更复杂的糖肽。总之,这一系列反应应该适合糖肽和糖蛋白及其去糖基化产物的合成。
