Abstract
A safe and operationally simple protocol for the preparation of β-d-glycosyl fluorides is presented. We demonstrate that a precise combination of XtalFluor-M, N-bromosuccinimide, and Et3N·3HF can mediate facile, high-yielding, and diastereoselective conversions of 2-O-acyl thioglycosides to β-d- and other 1,2-trans glycosyl fluorides. The key roles of these reagents are dissected in this work, as is the impact of their interplay on the fluorination stereoselectivity.

Abstract
The Galβ(1→4)Man disaccharide, found in the cell surface lipophosphoglycan (LPG) of Leishmania species, has been synthesized by a Ferrier glycosylation/cis-dihydroxylation strategy. This stereoselective method proved efficient for synthesizing the target saccharide in good yield. In addition, we prepared two clickable O-glycoside and phospho-glycoside versions of Galβ(1→4)Man to enable conjugation to protein carriers for further immunological and antibody-binding studies.

Abstract
Although D-allose (D-All) is a sugar with low natural abundance, it has great pharmacological and alimentary potential due to its biological properties. However, its chemistry, regarding the regioselectivity in protective reactions and glycosidations, has been scarcely explored. Glycobiological studies require appreciable quantities of carbohydrates with defined structures and high purity. Thus, the development of efficient strategies for their synthesis is crucial. In this frame, the knowledge of the regioselectivity between different hydroxyl groups of glycosyl acceptors is valuable because it allows minimizing the use of protecting groups. We have long been interested in the relative reactivity of OH-3 and OH-4 of glycosyl acceptors in glycosidation reactions. In this paper we synthesized D-allose glycopyranosyl acceptors with free OH-3 and OH-4 from D-Glc precursors. We assessed glycosidations with galactose trichloroacetimidates as donors and the experimental results were compared with those obtained by molecular modeling. Axial O-3 was the preferred site of glycosylation for α-anomers, whereas equatorial O-4 was the preferred site for a β-anomer. A good correlation between the experimental and modeling results was observed using atomic charges and cationic intermediates, although Fukui indices did not predict adequately the experimental results. The achieved regioselectivities are useful for the efficient design of oligosaccharide synthesis containing D-All moieties.

Abstract
Abstract
Simplexides are natural glycolipids isolated from the marine sponge Plakortis simplex, and contain alkyl 4-O-(α-D-glucopyranosyl)-β-D-galactopyranoside. Simplexides can release of cytokines (IL-6) and chemokines (CXCL-8) from human monocytes and cause the expansion of natural killer T-cells (iNKTs) in vitro, with iNKTs contributing to the sustenance of immune homeostasis. Herein, the stereoselective syntheses of S-glycosidic analogues, i.e. S-simplexides, are described. The routes included Lewis acid promoted anomerisation of glycosyl thiols and thioglycolipids, as well as anomeric S-alkylation. Synthesis of O-glycosidic analogues are included. Heptadecanyl O- and S-glycosides as well as the 17-tritriacontyl 4-O-(α-D-glucopyranosyl)-β-D-galactopyranoside, a component of the natural simplexide isolate, all induced IL-6 and CXCL-8 production at both 10 and 30 μg/mL concentrations from PBMCs whereas the two S-simplexides were inactive. It is speculated that the lack of activity for the S-disaccharide analogue could be due to inhibition of cellular α-glucosidase, preventing degradation of the simplex disaccharide to a simpler galactopyranoside, whereas lack of activity for the S-galactolipid analogue could be due to increased conformational flexibility of S-glycosides. On the other hand, simpler unbranched O- and S-glycolipid analogues were active. Natural simplexide, and a synthetic simplexide, the 18-pentatriacontanyl 4-O-(α-D-glucopyranosyl)-β-D-galactopyranoside, were more potent than the new compounds tested.

Abstract
The Pd-π-allyl intermediate in an electron-rich glycal system with poor reactivity is employed as an efficient glycosyl donor. Starting from glucal derived carbonate, various O-glycosides were formed via a palladium-catalyzed reaction through a tandem decarboxylation, proton abstraction, and nucleophilic addition, in good yields with excellent selectivity. Iterative glycosylation with the same strategy may provide an access to complex oligosaccharides.

Abstract
Does neighboring group participation actually enhance the reactivity of the anomeric center when the participating group is inherently disarming? To investigate the influence of the neighboring group effect from a 2-O protective group on acidic glycoside hydrolysis, 10 methyl glucosides having different protective groups on O2 have been synthesized and a clear trend between anomeric configuration, participation of the protective group, and the rate of hydrolysis could be observed.

Abstract
[reaction: see text] The synthesis of four bioactive analogues of the somatostatin (SRIF-14) mimetic, beta-d-glucoside (+)-2, in which the C1 indole side chain is replaced with indole surrogates, has been achieved. These congeners, possessing the naphthyl, benzothiophene, benzyl, and benzofuran substituents, were predicted to satisfy the electrostatic requirements of the tryptophan binding pocket of SRIF. Unlike the previously described C4 picolyl and pyrazinyl congeners, these ligands bind the hSST4 receptor.

Abstract
Derivatives of lactose with the galactose ring substituents replaced by deoxy or acylamino functions were prepared. The 2'-, 3'-, 4'- and 6'-deoxy, 3'-acetamido and 3'-benzamido derivatives of phenyl 4-O-(beta-D-galactopyranosyl)-beta-D-glucopyranoside (phenyl beta-lactoside) were synthesized from disaccharide or monosaccharide precursors. The derivatives were tested as substrates for the N-acetylglucosaminyltransferase from Neisseria meningitidis, which uses lactosyl derivatives as acceptors and UDP-GlcNAc as the donor in a beta-(1-->3) glycosylation reaction. The 6'-deoxy derivative was nearly threefold as active as phenyl beta-lactoside, whereas the 2'- and 4'-deoxy derivatives were less active. The other derivatives were inactive, as expected.

Abstract
The disaccharide beta-D-GlcA-(1-->4)-alpha-D-GlcNAc-1-->OMe and other small nonsulfated oligosaccharides related to heparin/heparan sulfate have been shown to bind to FGF and activated the fibroblast growth factor (FGF) signalling pathway in (F32) cells expressing the FGF receptor. Synthetic routes to beta-D-GlcA-(1-->4)-alpha-D-GlcNAc-1-->OMe and a glucose analogue beta-D-Glc-(1-->4)-alpha-D-GlcNAc-1-->OMe are described. The effects of these disaccharides on endothelial cell growth, which is relevant to angiogenesis, were evaluated and it was found they did not mimic the inhibitory effects that were observed for heparin albumin (HA) and that have also been observed by monosaccharide conjugates. They did not alter bovine aortic endothelial cell (BAEC) proliferation, in the presence of FGF-2 in serum free medium or in absence of FGF-2 in serum free and complete medium. Disaccharides (10 microg/mL) reduced by 25-31% the inhibition caused by HA (10 microg/mL) on BAEC growth in serum-free medium but had no effect in complete medium. There was no evidence obtained for the binding of these oligosaccharides to FGF-2 in competition with HA by ELISA.

Abstract
A highly stereoselective palladium-catalyzed O-glycosylation reaction is described. The reaction of a glycal 3-acetate or carbonate with the zinc(II) alkoxide of acceptors establishes the glycosidic linkage under palladium catalysis to give rise to disaccharides as the product in good yields and with high stereoselectivity. In contrast to the Lewis acid mediated Ferrier procedure, the anomeric stereochemistry of this reaction is controlled by the employed ligand. Whereas the use of a complex of palladium acetate and 2-di(tert-butyl)phosphinobiphenyl as the catalyst results in the exclusive beta-glycoside formation, the same reaction using trimethyl phosphite ligand furnishes an alpha-anomer as the major product. The utility of the 2,3-unsaturation present in the resulting glycoside is demonstrated by the further transformations such as dihydroxylation, hydration, and hydrogenation reactions. Thus, the combination of the glycosylation and subsequent functionalization provides a novel entry to saccharides which are otherwise difficult to prepare. The broad scope of the process, mildness of the reaction conditions, and experimental simplicity should make this method a useful tool in synthetic carbohydrate chemistry.

Abstract
A novel integrated bio- and chemocatalytic approach to the de novo catalytic asymmetric synthesis of saccharides has been developed. Acetoxypyranones obtained enantiopure by enzymatic resolution have been shown to undergo highly stereoselective palladium-catalyzed formal O-glycoside bond formation. The combination of these protocols can be applied to the iterative asymmetric catalytic synthesis of saccharides.
