Pentasaccharide repeating unit 20 of the lipoarabinomannan from the equine pathogen, Rhodococcus equi, and its dimer 31, were synthesized. The pentasaccharide was obtained by assembling a benzoylated 2,6-branched mannosyl trisaccharide acceptor 13 with a free hydroxyl group at C-2(') of the mannose residue attached to the core mannose residue by (1 [Formula: see text] 6)-linkage, followed by coupling with 2,3,5-tri-O-benzoyl-α-D-arabinofuranosyl-(1 [Formula: see text] 2)-3,4,6-tri-O-benzoyl-α-D-mannopyranosyl trichloroacetimidate (18), and by deacylation. Meanwhile, the decamer 31 was obtained by firstly preparing a benzoylated mannose (1 [Formula: see text] 6)-linked tetrasaccharide backbone 26 with 2-, 2'-O-ClAc, and 2(')-, 2?-O-Ac groups, respectively, then by dechloroacetylation and subsequent condensation with perbenzoylated trichloroacetimidate, and then by deacetylation and subsequent coupling with 18, and finally, by deacylation
