摘要

As an alternative to phthaloyl (Phth) group, 4, 5-dichlorophthaloyl (DCPhth) group was investigated as an amino protecting group to prove it to be useful for the synthesis of β- glycosides of 2-acetamido-2-deoxy glucose (GlcNAc). DCPhth was introduced onto the C-2 nitrogen of glucosamine to give 2, which was further transformed into mono-and di-and trisaccharide derivatives which constitute basic structural units of asparagine linked ...
