In the framework of studies towards oligosaccharide-conjugate-based vaccines against Streptococcus pneumoniae, the synthesis is reported of several spacer-containing oligosaccharides that represent parts of the capsular polysaccharide of S. pneumoniae serotype 6B, namely alpha-L-rhamnopyranosyl-(1-->4)-5-O-(3-aminopropyl hydrogen phosphate)-D-ribitol, 3-aminopropyl D-ribitol-(5-->hydrogen phosphat
