A highly α-stereoselective synthesis of oligosaccharide fragments of the VI antigen from salmonella typhi and their antigenic activities

In this paper, a convenient approach to the synthesis of the repeating α-(1→4)-linked N-acetyl galactosaminuronic acid units from the capsular polysaccharide of Salmonella typhi is reported. The exclusively α-stereoselective glycosylation reactions were a
