  N-Dimethylphosphoryl-protected glucosamine trichloroacetimidate as an effective glycosylation donor

  摘要：

  Glycosylation of a variety of alcohols with 3,4,6-tri-O-acetyl-2-N-dimethylphosphoryl-2-deoxy-alpha-D-glucopyranosyl trichloroacetimidate as a glycosyl donor provided the corresponding coupled products in high yields and good beta-selectivity. N-Dimethylphosphoryl-protection stayed stable under acidic and basic conditions for further elaboration of the glucosaminecontaining oligosaccharides. (c) 2007 Elsevier Ltd. All rights reserved.
