A general approach to C-Acyl glycosides via palladium/copper Co-catalyzed coupling reaction of glycosyl carbothioates and arylboronic acids

A general and efficient approach to the synthesis of various C-acyl glycosides has been developed via Pd2(dba)3/CuTC co-catalyzed cross-coupling reaction of glycosyl carbothioates with arylboronic acids. The reaction showed a broad s

Establishment of Guidelines for the Control of Glycosylation Reactions and Intermediates by Quantitative Assessment of Reactivity

Stereocontrolled chemical glycosylation remains a major challenge despite vast efforts reported over many decades and so far still mainly relies on trial and error. Now it is shown that the relative reactivity value (RRV) of thioglycosides is an indicator for revealing stereoselectivities according to four types of acceptors. Mechanistic studies show that the reaction is dominated by two distinct intermediates: glycosyl triflates and glycosyl halides from N-halosuccinimide (NXS)/TfOH. The formation of glycosyl halide is highly correlated with the production of α-glycoside. These findings enable glycosylation reactions to be foreseen by using RRVs as an α/β-selectivity indicator and guidelines and rules to be developed for stereocontrolled glycosylation.

IMPROVED PROCESS FOR PREPARATION OF 2,3,4,6-TETRA-O-BENZYL-D-GALACTOSE

Provided herein is an improved process for the preparation of benzylated derivative of D-galactose, particularly 2,3,4,6-tetra-O-benzyl-D-galactose that gives higher yield and better purity being cost effective with reduced impurities.

Addition of Organozinc Reagents to Glycopyranosyl Cyanides: Access to Keto Ester-C-glycosides or Unsaturated Acyl-C-glycosides

Addition of Reformatsky-type or allylic zinc reagents to 2,3,4,6-tetra-O-benzylglycopyranosyl cyanides led to keto ester-C-glycosides or unsaturated acyl-C-glycosides in moderate to excellent yields in the galactose, glucose, and mannose series.

Monosaccharidic mimetics of the sialyl LewisX tetrasaccharide based on 2,7-dihydroxynaphthalene

A potential monosaccharidic mimetic of the sialyl LewisX tetrasaccharide (sLeX) was identified based on an in silico docking study using the crystal structure of an E-selectin-sLeX complex. The chemical synthesis of the mimetic in an ortho-selective C-glycosylation is described. This compound and two close analogues were evaluated in a cell-based selectin binding assay where none of the tested mimetics showed an IC 50 below 1mM. This result can be explained by an unexpected 1C4 conformation of the mannosyl residue which precludes the required binding of the Ca2+-ion in E-selectin.

Novel glycolipid TLR2 ligands of the type Pam2Cys-α-Gal: Synthesis and biological properties

A more complete understanding of the mechanism of action of TLR agonists has fueled the investigation of new synthetic immunoadjuvants. In this context, we designed and synthesized glycolipids of the type Pam2Cys-α- Galactose as novel immunoadj

Synthesis of 1,2,3-triazole linked galactopyranosides and evaluation of cholera toxin inhibition

We report the synthesis of a series of bivalent 1,2,3-triazole linked galactopyranosides as potential inhibitors of cholera toxin (CT). The inhibitory activity of the bivalent series was examined (ELISA) and the series showed low inhibitory activity (millimolar IC50s). Conversely, the monomeric galactotriazole analogues were strong inhibitors of cholera toxin (IC 50 = 71-75 μM). The Royal Society of Chemistry 2011.
