Abstract
Glycosyl-N-allyl carbamates, obtained by reaction of anomerically unpr otected saccharides with allyl isocyanate, can be activated by an elec trophile-induced cyclisation and reacted with glycosyl accepters to fo rm the corresponding oligosaccharides. By this method the mucin core 2 trisaccharide(2) has successfully been synthesized. Due to the mild g lycosylation conditions even 1-O-acetyl protected glycosyl accepters c an be used. This was demonstrated in the synthesis of a 1,6-linked glu cosyl trisaccharide whereby a reptitious glycosylation strategy could be applied.
