  Synthesis of a C3-symmetric (1→6)-N-acetyl-β-d-glucosamine octadecasaccharide using click chemistry

  摘要：

  A C-3-symmetric (1-->6)-N-acetyl-beta-D-glucosamine octadecasaccharide was convergently synthesized on the basis of a copper(I)-catalyzed 1,3-dipolar cycloaddition reaction of azide and alkyne. The target octadecasaccharide showed good antitumor activity against H22 in the preliminary mice tests. (C) 2005 Elsevier Ltd. All rights reserved.

  日期：2003.3

  A (1 --> 6)-beta-D-glucosamine nonasaccharide was convergently synthesized using isopropyl thioglycosides as donors. Anomeric acetylated glucosamine derivatives were proved to be good acceptors in the NIS/TMSOTf catalyzed glycosylation. The target nonasaccharide showed a mild antitumor activity against H-22 on the preliminary mice tests. (C) 2003 Elsevier Science Ltd. All rights reserved.
