  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.
