The structure of the O-antigen polysaccharide of Salmonella thompson, serogroup C1 (6,7) has been investigated mainly by methylation analysis, n.m.r. spectroscopy, specific degradations by a phage-associated enzyme, N-deacetylation-deamination, and f.a.b.-m.s. It is concluded that the structure invo

✦ Synopsis
The structures of the O-specific side-chains in the lipopolysaccharides of Salmonella greenside, group Z, and Salmonella adelaide, group 0, have been investigated. The former proved to be identical with that of Escherichia coli 0 55. The latter, which was more extensively studied, was composed of repeating units having the structure
This was also shown to be the biological repeating-unit. The same structure has been proposed for the O-antigen of E. coli 0 111. The biological repeating-unit for the S. greenside O-antigen was also delined. The structural studies also confirmed that both lipopolysaccharides contain the hexose region typical for the Sulmonellu core.

Salmonella carrau, which belongs to group H (O:6, 14, 24) of the Kauffmann-White classification system, produced a major (90%) smooth lipopolysaccharide which by SDS-PAGE, glycose analysis, methylation, periodate oxidation, deamination, and 1H- and 13C-n.m.r. studies was shown to have an O-polysacch
## Abstract In this paper, a convenient approach to the synthesis of the repeating α‐(1→4)‐linked __N__‐acetyl galactosaminuronic acid units from the capsular polysaccharide of __Salmonella typhi__ is reported. The exclusively α‐stereoselective glycosylation reactions were achieved by using oxazoli
