Glycosyl radicals, produced under mild photoredox conditions, show unique utility in the preparation of C-linked glycoconjugates. We herein report the construction of -glycosidic bonds on α,β-dehydroalanine (DHA) of peptides with easily available glycosyl bromides as glycosyl radical precursors under highly anomeric control, leading to -glycosylation modifications of peptides. This method not only
在温和的光氧化还原条件下产生的糖基自由基在制备 C-连接糖复合物中显示出独特的用途。我们在此报道了在高度异头控制下,用容易获得的糖基溴作为糖基自由基前体在肽的α,β-脱氢丙氨酸(DHA)上构建β-糖苷键,从而导致肽的-糖基化修饰。该方法不仅具有出色的官能团相容性,而且在接近生理条件(水介质中pH ∼ 7和温度≤ 37 °C)下是可行的。
