Synthesis of some di- and trisaccharides related to the repeating unit of the antigen from Klebsiella type 20

Starting from D-galactose, D-glucuronolactone, and D-mannose, two trisaccharides and two disaccharides related to the repeating unit of Klebsiella type 20 have been synthesised using methyl triflate as promoter with success.
