ABSTRACT:
It is intended to chemically synthesize the trisaccharide moiety at the reducing end in the core sugar chain structure of an asparagine-linked glycoprotein. By using a highly inexpensive natural polysaccharide having a mannoseβ-1,4-bond as the starting material, a β-1,4-glycoside bond of mannose is formed.
