  日期：2003.5.1

  here a strategy for the synthesis of N-linked glycopeptide analogues that replace the glycosidic linkages extending from the core pentasaccharide with thioethers amenable to construction by chemoselective ligation. The key building block, a pentasaccharide-Asn analogue containing two thiol residues, was incorporated into CD52 by 9-fluorenylmethoxycarbonyl (Fmoc)-based solid-phase peptide synthesis. An

  我们在这里报告了一种合成 N 连接糖肽类似物的策略，该类似物用适合通过化学选择性连接构建的硫醚代替从核心五糖延伸的糖苷键。通过基于 9-芴基甲氧基羰基 (Fmoc) 的固相肽合成，关键构建块是包含两个硫醇残基的五糖-Asn 类似物。然后通过用 N-溴乙酰胺三糖对该糖肽进行烷基化，很容易生成十一糖模拟物。使用该技术完成了复杂类型 N 连接糖肽模拟物的快速组装。
• A new strategy for the synthesis of the core trisaccharide of asparagine-linked sugar chains

  日期：1996.11

  The core trisaccharide common to all asparagine-linked glycoprotein oligosaccharides was synthesized using two novel processes: 1) regioselective acetylation using lipase, and 2) inversion of the C-2 hydroxyl group of the glucose residue in a glucosyl chitobiose derivative to produce the corresponding mannosyl chitobiose derivative.

  Convenient synthesis of an N-glycan octasaccharide (A) of the bisecting type was described.
