  Synthesis of 1-deoxyhept-2-ulosyl-glycono-1,5-lactone utilizing α-selective O-glycosidation of 2,6-anhydro-1-deoxy-d-hept-1-enitols

  摘要：

  A series of 1-deoxy-heptulo-2-pyranosyl-glycono-1,5-lactones were synthesized utilizing completely a-selective O-glycosidation of heptenitols. Anomeric configuration of the products was confirmed by (3)J(C,H) coupling measurement and X-ray crystal structural analysis. The benzyl-protected ketosyl saccharides were partly unstable, and glycosidic linkage was prone to cleave under the usual debenzylation conditions. To prevent this, we surveyed various additives for the Pd-catalyzed hydrogenation reaction and found that basic alumina was the most effective. (c) 2006 Elsevier Ltd. All rights reserved.

  This makes glycopeptides an interesting class of compounds for medical applications. To enhance the long‐term availability of these molecules in vivo, the stabilization of the glycosidic bond between the amino acid residue and the carbohydrate is of interest. The described modular approach affords β‐linked C‐glycosyl amino acids by a sequence of Petasis olefination of glyconolactones, stereoselective

  O-糖基化是蛋白质翻译后最重要的修饰之一。碳水化合物对肽主链的附着会影响缀合物的构象以及溶解度，甚至对于在细胞间相互作用中与特定配体结合或在膜上进行主动转运而言，甚至是必不可少的。这使糖肽成为医学应用中有趣的一类化合物。为了提高这些分子在体内的长期可用性，关注氨基酸残基和碳水化合物之间糖苷键的稳定化。所描述的模块化方法提供了β-连接的C糖基氨基酸，包括糖基内酯的Petasis烯化反应，立体选择性硼氢化反应和轻度的B-烷基-Suzuki偶联反应。偶联产物被转化为适合固相合成的C-糖基氨基酸结构单元，并成功地掺入了与肿瘤相关的MUC1-糖肽的部分序列中。由此产生的C糖肽是O糖肽疫苗长期稳定模拟物开发的候选对象。
