  Synthesis of chondroitin sulfate E octasaccharide in a repeating region involving an acetamide auxiliary

  摘要：

  Chondroitin sulfate E repeating octasaccharide was effectively synthesized in a stereocontrolled manner by adopting an acetamide-type disaccharide unit. In the tetrasaccharide synthesis we isolated a characteristic glycosyl imidate as a reactive intermediate. An acetamide auxiliary involves the glycosylation mechanism. (c) 2007 Elsevier Ltd.
