Synthese der heptose- und kdo-haltigen trisaccharidkette der inneren core-region von lipopolysacchariden in immunogener form
摘要:
An effective synthesis of the alpha-allylglycoside 13 of the trisaccharide L-alpha-D-Hep-(1 --> 3)-L-alpha-D-Hep-(1 --> 5)-alpha-Kdo is developed using the trichloracetimidate method. The trisaccharide 14 carrying a cysteamine spacer is copolymerized with acrylamide to polymer 16 containing the trisaccharide 13 in immunogenic form.
