  Synthesis of fully and partially benzylated glycosyl azides via thioalkyl glycosides as precursors for the preparation of N-glycopeptides

  摘要：

  Fully O-benzylated mono-, di- and trisaccharide glycosyl azides representing the reducing terminal of the core structure of N-glycans were synthesized. Totally and partially benzylated thioalkyl glucosamine glycosides were converted into the corresponding glycosyl azides with trimethylsilyl azide in the presence of methyl triflate. The beta-mannosidic linkage was created by C-2 epimerization of the initially introduced beta-D-gluco-unit via oxidation followed by stereoselective reduction with tetrabutylammonium borohydride.

  method for macrocyclic glycopeptide synthesis was developed and utilized to synthesize tyrocidine A and its glycosylated derivatives. The method is based on solid-phase peptide synthesis using 2-chlorotrityl resin as the solid-phase support and glycosyl amino acids as building blocks. After glycopeptides with fully protected glycans and side chains were released from the acid-labile resin, their C- and

  开发了一种有效且实用的大环糖肽合成方法，并将其用于合成酪氨酸A及其糖基化衍生物。该方法基于固相肽合成，其中2-氯三苯甲基树脂为固相载体，糖基氨基酸为结构单元。从酸不稳定的树脂中释放出具有完全保护的聚糖和侧链的糖肽后，它们的C-和N-末端在溶液中分子内偶联，以定量产率提供环状糖肽。该合成方法通常应适用于各种大环糖肽。合成酪氨酸A衍生物的生物学研究表明，将聚糖直接连接到酪氨酸A的Asn残基上可减少其抗菌活性，但通过简单的间隔子将聚糖连接到Asn却没有。这些结果揭示了聚糖对糖肽抗生素的活性，可能还有其结构的重要影响。
