Streptococcus pneumoniae LTA is a highly complex glycophospholipid that consists of nine carbohydrate residues: three glucose, two galactosamine and two 2-acetamino-4-amino-2,4,6-trideoxygalactose (AATDgal) residues that are each differently linked, one ribitol and one diacylated glycerol (DAG) residue. Suitable building blocks for the glucose and...

... Reaction of 89 with glucose imidate donor 90 was performed under TMSOTf catalysis at −45 • C in propionitrile as a participating solvent to afford the desired β linked trisaccharide intermediate 91 with selectivity of 5:1 β/α ratio. This trisaccharide fragment was also synthesized by the same group, specifically to study its biological property [57]. Phosphorylation of this trisaccharide with bis(diisopropylamino)cyanoethoxyphosphine in the presence of diisopropylammonium tetrazolide furnished phosphorylated trisaccharide 92 in good yield as outlined in Scheme 11. ...
