P. Sengupta et al., Synthesis of a di- and a trisaccharide related to the repeating unit of E.coli O128 lipopolysaccharide, J CARB CHEM, 19(2), 2000, pp. 243-251
Starting from L-fucose, D-galactose and 2-amino-2-deoxy-D-galactose, methyl
2-acetamido-2-deoxy-beta-D-galactopyranosyl-(1-->4)-alpha-D-galactopyranos
ide and methyl 2-acetamido-2-deoxy-beta-D-galactopyranosyl-( 1 --> 6)-[alph
a-L-fucopyranosyl-(1-->2)]-beta-D-galactopyranoside, which are related to t
he repeating unit of E. coli O128, have been synthesized using NIS and TfOH
as promoter.
