Abstract

The pentasaccharide repeating unit containing 6-deoxy-l-talose corresponding to the cell wall O-polysaccharide of Escherichia coli (E. coli) O66 strain has been successfully synthesized in very good yield using sequential glycosylations of judiciously functionalized monosaccharide intermediates. Incorporation of the β-d-mannosidic linkage and 6-deoxy-α-l-talose in the pentasaccharide was achieved in excellent yield.
