  Orthogonal Sulfation Strategy for Synthetic Heparan Sulfate Ligands

  摘要：

  An orthogonal sulfation strategy involving six different protecting groups has been developed for generating sulfated carbohydrate libraries based on heparan. Chemoselective cleavage conditions (optimized for a heparan disaccharide) can be performed in the presence of sulfate esters as well as the remaining protecting groups.
