probing several processes. Herein we report a one-pot, three-component sequential procedure for the synthesis of a novel class of glyco-conjugates, i.e.glyco-hydantoin conjugates, in high yields and very mild conditions, using readily accessible starting materials. We also demonstrated that some of the glyco-hydantoin conjugates obtained are synthons for the preparation of a novel class of glyco-pseudopeptides
将糖与杂环和肽连接的新方法的开发是一个有吸引力的研究领域,因为糖结合物在
生物学和医学中起着重要的作用,并且是探测多个过程必不可少的工具。本文中,我们报告了一种易于使用的起始原料,以高收率和非常温和的条件合成一类新型的糖共轭物(即糖乙内酰
脲衍
生物)的一锅,三组分顺序程序。我们还证明,获得的某些糖-乙内酰
脲共轭物是合成新型糖-伪肽的合成子,其中
氨基酸通过乙内酰
脲环被束缚到糖上。
