Preparation of heparin/heparan sulfate oligosaccharides with internal N-unsubstituted glucosamine residues for functional studies.

abstract：:A straight forward synthesis of a heptasaccharide part of the cell-wall lipopolysaccharide of Mycobacterium gordonae strain 990, known to have antigenicity, has been achieved in excellent yield. Judicious choice of protecting groups in the intermediates played a significant role throughout the synthesis. Most of the i...
