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

D-核糖醇。
磷酸化使用H-
