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.
