A group of fluorescent statistical glycopolymers, prepared via reversible addition-fragmentation chain-transfer (RAFT)-based polymerizations, were successfully employed in lectin-mediated bacterial binding studies. The resultant glycopolymers contained three different monomers: N-(2-hydroxyethyl) acrylamide (HEAA), N-(2-aminoethyl) methacrylamide (AEMA) and N-(2-glyconamidoethyl)-methacrylamides possessing different pendant sugars.

The identity of the crystalline product formed by the acetylation of a mixture of methyl alpha- and beta-D-glucopyranuronates has been confirmed as being methyl 1,2,3,4-tetra-O-acetyl-beta-D-glucopyranuronate (3), which agrees with the assignment from 1H NMR. The absolute configuration of compound 3

D-Glucose 3- and 6-[sodium 2-(perfluoro-hexyl or -octyl)ethyl phosphates) have been synthesized by condensation of 1,2,3,4,-tetra-O-acetyl-beta-D-glucopyranose and 1,2:5,6-di-O-isopropylidene-alpha-D-glucofuranose with 2-(perfluoroalkyl)ethylphosphoroditriazolides followed by O-deacetylation or deacetalation. The structures of the compounds were established on the basis of 1H-, 19F-, 31P-, and 13C-NMR

The single-crystal X-ray diffraction and high-resolution 1H and 13C NMR spectral data for methyl 2,5-di-O-acetyl-beta-D-glucofuranosidurono-6,3-lactone and 1,2,5-tri-O-acetyl-beta-D-glucofuranurono-6,3-lactone are reported. The lactones were synthesized as byproducts of reactions carried out to obtain methyl 1,2,3,4-tetra-O-acetyl-D-glucopyranuronate. The conformations of these lactones in the
