  Design and Synthesis of Unnatural Heparosan and Chondroitin Building Blocks

  摘要：

  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.

  A simple and convenient method for the esterification of various monosaccharide and disaccharide uronic acids, derived from glucose, galactose and mannose, was developed with different alcohols using the eco-friendly catalyst silica-sulphuric acid (H2SO4-SiO2). The esterification reactions proceeded at room temperature under mild conditions with excellent yields. Under the standard reaction conditions

  使用环保催化剂二氧化硅-硫酸（H 2 SO 4 -SiO 2），开发了一种简便的酯化方法，用于由葡萄糖、半乳糖和甘露糖衍生的各种单糖和二糖糖醛酸与不同醇的酯化反应。酯化反应在室温下温和条件下以优异的产率进行。在标准反应条件下，对乙酰基、苯甲酰基、新戊酰基、异亚丙基、苄基、萘基等各种敏感保护基团具有良好的耐受性。部分保护的糖醛酸在不发生自缩合反应的情况下进行酯化。
