  硼酸酯作为碳水化合物化学中的保护基：糖苷衍生的硼酸酯的酰化，甲硅烷基化和烷基化过程†

  摘要：

  选择性安装酰基，甲硅烷基醚和对位的程序已经开发了使用苯基硼酸酯作为受保护的中间体的对糖苷底物的-甲氧基苄基（PMB）醚基。硼酸酯形成，官能化和脱保护的顺序仅需一个纯化步骤即可完成，脱硼后可回收并再利用硼酸组分。关键的进展包括确定在硼酸酯存在下安装PMB基团的反应条件，以及霍尔和同事开发的“相转换”规程作为硼酸酯裂解的有效方法的使用。硼酸酯脱保护的相对温和的条件可耐受几个官能团，包括酯，甲硅烷基醚，缩酮和硫代糖苷。

• Acylation of carbohydrates over Al2O3: preparation of partially and fully acylated carbohydrate derivatives and acetylated glycosyl chlorides
  作者：Pallavi Tiwari、Anup Kumar Misra

  日期：2006.2

  protocol does not require the addition of any base or activator. This methodology has been further extended to the selective acylation of carbohydrate diols and the one-pot preparation of acetylated glycosyl chlorides direct from free reducing sugars. The yields obtained in most of the cases are excellent.

  据报道，使用酰氯和固体支持剂Al2O3对碳水化合物衍生物进行选择性和全O酰化。该协议不需要添加任何碱或活化剂。该方法已经进一步扩展到碳水化合物二醇的选择性酰化和直接从游离还原糖直接制备一锅乙酰化糖基氯的方法。在大多数情况下所获得的产量是极好的。

  for the synthesis of a pentasaccharide present in the O-antigen of Salmonella enterica O57 and Escherichia coli O51 strains. A sequential glycosylation strategy has been adopted for the synthesis of the target pentasaccharide. All intermediate steps are high yielding and the glycosylation steps are stereoselective. A number of recently developed methodologies have been used in the synthesis.

  The synthesis of hyaluronan dimers and tetramers equipped with a 4-methylumbelliferyl group at the reducing end to potentially allow monitoring of hyaluronidase activities is described. The 4-OH at the non-reducing glucuronate in the presented series is either removed or methylated to prohibit transglycosylase reactions, leading to a total of four probes. (C) 2011 Elsevier Ltd.

• Design and Synthesis of Unnatural Heparosan and Chondroitin Building Blocks
  作者：Smritilekha Bera、Robert J. Linhardt

  DOI：10.1021/jo200076z

  日期：2011.5.6

  Triazole linked heparosan and chondroitin disaccharide and tetrasaccharide building blocks were synthesized in a stereoselective manner by applying a very efficient copper catalyzed azide-alkyne cycloaddition (CuAAC) reaction of appropriately substituted azido-glucuronic acid and propargyluted N-acetyl glucosamine and N-acetyl galactosamine derivative, respectively. The resulting suitably substituted tetrasaccharide analogues can be easily converted into azide and alkyne unit for further synthesis of higher oligosaccharide analogues.

  Partially protected thioglycuronic acids are prepared efficiently by chemo- and regioselective oxidation of the corresponding thioglycosides using the TEMPO/BAIB reagent combination. After esterification, the thioglycuronic acids proved to be useful as both donor and acceptor in sulfonium-mediated condensations toward acidic di- and trisaccharides.
