A route for the synthesis of glycuronamides via the intermediacy of 6-S-tolyl-glycosides and uronic acid thioesters, is reported. The route, which is compatible with a variety of carbohydrate residues and protecting groups, was used to synthesize the repeating unit of the E. coli K54 capsular...

Mycobacteria, including the human pathogen Mycobacterium tuberculosis the causative agent of tuberculosis, produce a complex cell wall structure made of carbohydrates and lipids. The major structural element of the mycobacterial cell wall is a glycoconjugate called the mycolic...

The O-methyl phosphoramidate (MeOPN) motif is a non-stoichiometric modification of capsular polysaccharides (CPS) in ~70% of all Campylobacter jejuni strains. Infections by C. jejuni lead to food-borne illnesses and the CPS they produce are key virulence factors. The MeOPN phosphorus atom in...

Cyclic tetraaryl[5]cumulenes (1a–f) have been synthesized and studied as a function of increasing ring strain. The magnitude of ring strain is approximated by the extent of bending of the cumulenic core as assessed by a combination of X-ray crystallographic analysis and DFT calculations. Trends...
