A series of alkyl thioglycosides and alkyl thiodiglycosides bearing glucose and N-acetylglucosamine residues were prepared by thiol-ene coupling in moderate to good yields (40-85%). Their binding ability towards wheat germ agglutinin was measured by competitive enzyme-linked lectin assays. One of the synthetic compounds presenting two GlcNAc units showed the highest inhibitory effect of this study with an IC50 of 11 μM corresponding to a 3182-fold improvement compared to GlcNAc. These synthetic molecules were used to produce giant vesicles, alone or in mixture with phospholipids, mimicking bacterial outer membrane vesicles (OMV) with potential antiadhesive properties.

Here we report a method for the preparation of anomerically pure β-S-glycopyranosides (1,2-trans-glycosides) from the corresponding peracetate donors. S-glycosylation was performed in CHCl3 at reflux in the presence of a catalytic amount of InBr3. Deacylation of the intermediate peracetates were achieved under Zemplén conditions. Five pyranose examples, monosaccharides D-glucose and D-galactose and disaccharides cellobiose, maltose, and lactose, were used as donors, and five thiols including an α/ω dithiol and Fmoc-L-cysteine were used as acceptors. Melting points, high res MS, [α]D and NMR data (1H and 13C, including COSY, HSQC and HMBC) are reported for compounds not previously described.
Ampiphilic Carbohydrate-Based Mesogens, VI: Synthesis of a Series of Alkyl 1-Thio-D-glucopyranosides and Their Regioselective Reductions to 1-Alkylthio-1-deoxy-D-glucitols

Alkyl 1-thio-α,β-D-glucopyranosides (hexyl to decyl, 1a-e) are prepared by reaction of penta-O-acetyl-β-D-glucopyranose with the respective thiols in the presence of diethylether-trifluoroborane, followed by deacetylation. 1a-e are converted into their tetra-O-diethylboryl derivatives 2a-e and reduced with ethyldiboranes(6) in the presence of the catalyst 9-methylsulfonyloxy-9-borabicyclononane (9-BBN-mesylate, MSBBN) to give the mesogenic 1-alkylthio-1-deoxy-D-glucitols 3a-e after deboronation.
