In the framework of studies towards oligosaccharide-conjugate based vaccines against Streptococcuspneumoniae, the synthesis is reported of four spacer-containing tetrasaccharides that each can be conceived as representing a repeating unit of the capsularpolysaccharide of S. pneumoniae serotype 6B, namely, 3-aminopropyl D-ribityl-(5-->hydrogen phosphate-->2)-alpha-D-galactopyranosyl-(1-->3) -alph
