  Synthesis of Differentially Protected Glucosamine Building Blocks and Their Evaluation as Glycosylating Agents

  摘要：

  The modular assembly of heparin oligosaccharides requires glucosamine building blocks with amine protecting groups for a-selective glycosylations that can be readily removed. The synthesis of N-4-nitrobenzensulphonamide (nosyl)- and N-2,4-dinitrophenyl (DNP)-protected glucosamine building blocks and their evaluation as glycosylating agents is described. The N-nosyl-protected glucosamine building blocks were challenging to prepare and their glycosylations resulted in inseparable mixtures of products. The N-DNP-protected glucosamines, however, were readily synthesized and resulted in a-selective couplings to protected L-iduronic acid derivatives.

  Abstract The selective N-sulfation of 2-amino-2-deoxy-D-glucopyranose derivatives having unprotected hydroxyl groups with phenyl chlorosulfate and triethylamine in anhydrous organic solvent followed by addition of aqueous sodium bicarbonate affords high yields of the 2-deoxy-2-sulfoamino-D-glucopyranose products.
