The discovery of novel conditions for highly β-stereoselective (>9 : 1) mannosylation of OH-2 of mannosides using a straightforward perbenzylthioglycoside donor has allowed ready assembly of β-mannosyl oligosaccharides including the repeating trisaccharide motif of the O5 antigen of pathogen Klebsiella pneumoniae.
