A synthesis of the pentenyl glycoside of the tetrasaccharide side chain from the major glycoprotein of Bacillus anthracis by a [3 + 1] approach is described. The construction of the 1,2-trans-glycosidic linkage in the terminal anthrose moiety was achieved through the application of known α-nitrilium ion-mediated β-selectiveglycosylation methodology. An iterative glycosylation strategy was used for

The process for selecting potent and effective carbohydrate antigens is not well-established. A combination of synthetic glycan microarray screening, surface plasmon resonance analysis, and saturation transfer difference NMR spectroscopy was used to dissect the antibody-binding surface of a carbohydrate antigen, revealing crucial binding elements with atomic-level detail. This analysis takes the first step toward uncovering the rules for structure-based design of carbohydrate antigens.
