Syntheses of two oligosaccharides as methyl glycosides related to the repeating unit of S. enteritidis capsular polysaccharide (CPS) are presented. The trisaccharide corresponds to the backbone of the CPS whereas the tetrasaccharide is a model for the repeating unit which has a branched structure. Molecular dynamics simulations investigating their flexibility and dynamics revealed that the oligosaccharides populate several conformational states and indicate that conformational averaging should be used in describing the accessible conformational space.
