  Synthesis of novel glycolipids derived from glycopyranosyl azides and N-(β-glycopyranosyl)azidoacetamides

  摘要：

  A general and expedient method based on a click reaction has been developed for the synthesis of novel glycolipids. The Cu(I) catalyzed [3+2] cycloaddition of several fully acetylated beta- as well as alpha-D-glycopyranosyl azides, including the 1,6-diazide derived from D-glucose, with long chain alkyl propargyl ethers gave the respective 1,4-substituted 1,2,3-triazole derivatives in good yields. Treatment of fully acetylated N-(beta-glycopyranosyl)azidoacetamides under similar conditions with alkyl propargyl ethers afforded the 1,2,3-triazolylacetamido derivatives in fairly good yields. Zemplen de-O-acetylation of all the fully acetylated derivatives furnished the free glycolipids in quantitative yields. (c) 2008 Elsevier Ltd. All rights reserved.
