Inhoud: Syntheses are described of the three disaccharides: methyl 3-O-L-glycero-α-D-manno-heptopyranosyl-L-glycero-α-D-manno-heptopyranoside 4-phosphate, methyl 3-O-(L-glycero-α-D-manno-heptopyranosyl 4-phosphate)-L-glycero-α-D-manno-heptopyranoside, and methyl 3-O-(L-glycero-α-D-manno-heptopyranosyl 4-phosphate)-L-glycero-α-D-manno-heptopyranoside 4-phosphate together with their 2-(4-trifluoroacetamidophenyl)ethyl glycoside analogues. These correspond to phosphorylated structures found in the inner core region of lipopolysaccharides from Salmonella. The known derivative methyl 6,7-di-O-acetyl-2,3,4-tri-O-benzyl-L-glycero-α-D-manno-heptopyranoside was used as a common heptose precursor. Phosphorylation on suitably protected disaccharide derivatives was performed by treatment with phosphorus triimidazolate in dichloromethane followed by the addition of benzyl alcohol and in situ oxidation with m-chloroperbenzoic acid to give the dibenzyltriester phosphate derivatives, which after deprotection gave the target compounds.
