Synthesis of Some DI- and Trisaccharides Related to the Repeating Unit of the Antigen from Klebsiella Type 20

Abstract 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.
