The present invention relates to the total chemical synthesis of the monosaccharide 35# (R' = H), the disaccharide 36# (R' ≠ H; R'' = H), the trisaccharide 37# (R' ≠ H; R'' ≠ H; R''' = H) and the tetrasaccharide 1#(R' ≠ H; R'' ≠ H; R''' ≠ H) of the following general formula wherein R represents –Y–NH2 Y represents a linker R' is H or R'' is H or R''' is H or of the lipopolysaccharide from Neisseria meningitidis, as well as to the trisaccharide 37# and the tetrasaccharide 1#, to vaccines containing at least one of the saccharides 1#, 35#, 36#, and 37# and to the use of such vaccine for immunization against diseases caused by infection with bacteria containing the tetrasaccharide α-GlcNAc-(1→2)-α- Hep-(1→3)-α-Hep-(1→5)-α-Kdo or the trisaccharide α-Hep-(1→3)-α-Hep-(1→5)-α- Kdo or α-GlcNAc-(1→2)-α-Hep-(1→3)-α-Hep, especially for immunization against meningitis, septicaemia, pneumonia and nasopharyngitis caused by Neisseria meningitidis.
