2-(p-Trifluoroacetamidophenyl)ethyl and methyl glycosides of a tetrasaccharide repeating unit corresponding to that of the Shigella dysenteriae type 1 cell wall lipopolysaccharide, of a rhamnosylrhamnosylgalactose trisacchride, and of a rhamnosylrhamnose and a rhamnosylgalactose disaccharides are described. The main glycosylation method used was activation of thioglycosides with dimethyl(methylthio)sulfonium triflate (DMTST).
