High Mannose

An efficient synthesis of the nonamannoside residue 1 of high mannose glycoproteins was achieved using an oligomer-supported solution synthesis with low-molecular-weight polyethylene glycol as the anchor. The synthesis required only five coupling steps from only two monosaccharide building blocks with an overall yield of 12%.Key words: nonamannoside, oligosaccharide synthesis, soluble polymer support synthesis, glycoproteins.
