Synthesis of Glycosyl Chlorides and Bromides by Chelation Assisted Activation of Picolinic Esters under Mild Neutral Conditions

A general method has been developed for the formation of glycosyl chlorides and bromides from picolinic esters under mild and neutral conditions. Benchtop stable picolinic esters are activated by a copper(II) halide species to afford the corresponding products in high yields with a traceless leaving group. Rare β glycosyl chlorides are accessible via this route through neighboring group participation. Additionally, glycosyl chlorides with labile protecting groups previously not easily accessible can be prepared.

Gram scale synthesis of A (type 2) and B (type 2) blood group tetrasaccharides through 1,6-anhydro-N-acetyl-β-D-glucosamine

Gram scale synthesis of A (type 2) and B (type 2) tetrasaccharides in the form of 3-aminopropyl glycosides is proposed starting from 3-O-benzoyl-1,6-anhydro-N-acetylglucosamine. Its galactosylation followed by re-protection gave lactosamine derivative with single free 2′-OH group in total yield 75%. Standard fucosylation and next run of re-protection in total yield 88% gave a trisaccharide Fuc-Gal-anhydroGlcNAc with single free 3′-OH group. Its standard α-galactosylation gave protected B (type 2) tetrasaccharide. For synthesis of correspondent A tetrasaccharide seven different 2-azido-2-deoxygalactosyl (GalN3) donors were tested: 6-O-acetyl-3,4-O-isopropylidene-GalN3 thioglycoside was shown to provide the best yield (89%) and stereoselectivity (α/β = 24:1). Further 1,6-anhydro cycle opening, spacer-arming and complete deprotection resulted in the target 3-aminopropyl glycosides of A (type 2) and B (type 2) tetrasaccharides, yields 87 and 85% correspondingly.

Synthesis of new sulfonic acid-containing oligosaccharide mimetics of sialyl Lewis A

Two trisaccharides as new sulfonic acid mimetics of the sialyl Lewis A tetrasaccharide were synthesized. The natural sialic acid residue is replaced by a C-sulfonic acid moiety attached to position C-3′ of the lactosamine unit of the mimetics. The l-fucos

From disulfide- to thioether-linked glycoproteins

(Chemical Presented) Strengthening the bond: The introduction of a thiol tag in combination with chemoselective ligation to form a disulfide-linked bioconjugate is a selective and useful method for site-selective protein glycosylation. The phosphine-mediated desulfurization of such glycoconjugates to their reductant-resistant thioether-linked counterparts completes a convergent, site-selective synthesis of thioether-linked glycoproteins (see scheme).

The conformational behaviour of fucosyl and carbafucosyl mimetics in the free and in the protein-bound states

The conformational behaviours of fucosyl glycosides bearing a glyceryl aglycon and their corresponding carbafucosyl glycomimetics have been studied both in aqueous solution and when bound to a fucose-specific lectin (Aurelia Aurantia Agglutinnin), using a combination of NMR spectroscopy (J and NOE data) and molecular mechanics calculations. Analogies and differences between the mimetics and the natural compounds have been found.
