O-β-D-Mannopyranosyl-(1 → 4)-O-α-D-mannopyranosyl-(1 → 3)-L-rhamnopyranose, a trisaccharide including a repeating unit of the O-specific polysaccharide (OSP) of Bulkholderia vietnamiensis strain LMG 6988, and O-(2-acetamido-2-deoxy-β-D-mannopyranosyl)-(1 → 4)-O-α-D-galactopyranosyl-(1 → 4)-D-galactopyranose, a trisaccharide including a repeating unit of OSP of Acinetobactor baumannii serogroup O18, were synthesized by means of in-situ-activating glycosylation using 2-O-acetyl-3,4,6-tri-O-benzyl-D-glucopyranose (2ATBG) and a reagent mixture of p-nitrobenzenesulfonyl chloride, silver triflate, and 1,8-diazabicyclo[5.4.0]undec-7-ene, and related systems. New syntheses of 2ATBG, allyl 2,3,6-tri-O-benzyl-α-D-galactopyranoside, benzyl 2,3,6-tri-O-benzyl-α-D-galactopyranoside, and 2-azido-3,4,6-tri-O-benzyl-2-deoxy-D-mannopyranose are described.
