A new dehydrative glycosylation reaction has been established by capitalizing on the comproportionation reaction of 2-aryl-1,3-dithiane 1-oxides promoted by triflic anhydride (Tf2O). By wedding the high potency of thiophilic promoter system with the step efficiency of dehydrative glycosylation, this reagent underwent facile intermolecular oxothio acetalization with C1-hemiacetal donor to install a temporary leaving group, rendering a transient electrophilic center at the remote site to the anomeric position. The sulfenyl triflate tethered at the terminus concomitantly activated the sulfide intramolecularly to afford the oxocarbenium ion, thereby facilitating the title glycosylation. Aside from accommodating broad range functional groups and inactive hemiacetal substrates, the present activation protocol also proved expedient for 1,3-diol protection. Most importantly, this method further provided a fresh perspective for the application of sulfur chemistry to carbohydrate chemistry.

A novel and high yielding glycosylation protocol with glycosyl ortho-alkynylbenzoates as donors and iodine as promoter is described. The donors are stable and can be chemoselectively activated in the presence of thioethyl and thiophenyl glycosides. The application of this methodology in one-pot consecutive glycosylation reaction is described.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Recommanded Product: 2,3,4,6-Tetra-o-acetyl-D-glucopyranose, you can also check out more blogs about10343-06-3

Surfactants are not only pivotal constituents in any biological organism in the form of phospholipids, they are also essential for numerous applications benefiting from a large, internal surface, such as in detergents, for emulsification purposes, phase transfer catalysis or even nanoparticle stabilization. A particularly interesting, green class of surfactants contains glycoside head groups. Considering the variability of glycosides, a large number of surfactant isomers become accessible. According to established models in surfactant science such as the packing parameter or the hydrophilic lipophilic balance (HLB), they do not differ from each other and should, thus, have similar properties. Here, we present the preparation of a systematic set of glycoside surfactants and in particular isomers. We investigate to which extent they differ in several key features such as critical aggregation concentration, thermodynamic parameters, etc. Analytical methods like isothermal titration calorimetry (ITC), tensiometry, dynamic light scattering (DLS), small angle-X-ray scattering (SAXS), transmission electron microscopy (TEM) and others were applied. It was found that glycosurfactant isomers vary in their emulsification properties by up to two orders of magnitude. Finally, we have investigated the role of the surfactants in a microemulsion-based technique for the generation of zinc oxide (ZnO) nanoparticles. We found that the choice of the carbohydrate head has a marked effect on the shape of the formed inorganic nanocrystals.

A co-crystallised sample of alpha- and beta-2,3,4,6-tetra-O-acetyl-d- glucopyranose [alpha:beta = 1:2.86(8)], (alpha,beta-1), has been isolated from a solution of 2,3,4,6-tetra-O-acetyl-d-glucopyranose in moist ethyl acetate/diethyl ether. In contrast, pure beta-2,3,4,6-tetra-O-acetyl-d- glucopyranose, (beta-1) was isolated on crystallisation from diethyl ethyl/petroleum ether. Species (alpha,beta-1) is a solid solution in which approximately one in four of the molecules in the beta-form is randomly substituted by a molecule of the alpha-anomer. The hydrogen bonded zig-zag chain connectivity of the pure beta-anomer is maintained in the solid solution along the b direction. Since the parent d-glucopyranose compounds differ in their molecular packing and, therefore in structure, the solid solution phenonmenon in the case of their tetraacetyl derivatives is unexpected. Compound (beta-1) and the (alpha,beta-1) solid solution crystallize in the orthorhombic space group P212121: a = 7.8612(4) A, b = 10.2045(5) A, c = 20.7362(11) A, and Z = 4 for (beta-1) at 120(2)K; and a = 7.9674(5) A, b = 10.2547(4) A, c = 21.1565(10) A, and Z = 4 for (alpha,beta-1) at 291(2) K.

Glycoconjugation is a promising modification strategy for the optimization of peptide drugs. In this study, five different monosaccharide derivatives (7a-e) were covalently linked to the N-terminal of R-lycosin-I, which yielded five glycopeptides (8a-e). They demonstrated increased or reduced cytotoxicity depending on monosaccharide types, which might be explained by the changes of physicochemical properties. Among all synthesized glycopeptides, only 8a exhibited increased cytotoxicity (IC50 = 9.6 ± 0.3 muM) and selectivity (IC50 = 37.4 ± 5.9 muM). The glucose transporter 1 (GLUT1) with high expression in cancer cells was approved to be involved in the cytotoxicity and selectivity enhancement of 8a. Furthermore, 8a but not R-lycosin-I inhibited tumor growth in the nude mice xenograft model without generating side effects intraperitoneally. Taken together, this study reveals the different monosaccharide roles in peptide modification and also provides an optimized anticancer peptide with high activity and selectivity, that is, 8a might be a promising lead for developing anticancer drugs.

Kaempferol 3-O-(3?,6?-di-O-E-p-coumaroyl)-beta-d- glucopyranoside (1), an optimal metabolite of Scots pine seedlings for protection of deep-lying tissue against damaging UV-B, represents a typical acylated flavonol 3-O-glycoside. This compound was synthesized for the first time via two approaches. The first approach, starting with kaempferol, featured formation of the flavonol 3-O-glycosidic linkage with a glycosyl bromide under conventional PTC conditions. In the second approach, 5,7,4?-tri-O-benzyl- kaempferol was readily prepared from 2?,4?,6?- trihydroxyacetophenone and p-hydroxybenzoic acid, which was coupled with a glucopyranosyl o-hexynylbenzoate under the catalysis of a gold(I) complex to provide the desired 3-O-glycoside in excellent yield. A variety of the glycosyl o-hexanylbenzoates equipped with the 2-O-benzoyl group were also proven to be highly efficient donors for construction of the flavonol 3-O-glycosidic linkages.

A method for photochemical activation of glycosyl donors is presented. Selenoglycosides were activated by single-electron transfer using a photooxidant, N-methylquinolinium hexafluorophosphate, as photosensitizer and a toluene cosolvent as cosensitizer under irradiation at 350 nm. In this way we were able to synthesize glycosides including (1?6)-linked disaccharides. Benzyl ethers and benzoate esters were compatible with these conditions, allowing potentially synthetically useful transformations. The major by-products were due to hydrolysis; the reactions required the presence of oxygen and were run in air.

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 beta 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.

In eukaryotic protein N-glycosylation, a series of glycosyltransferases catalyse the biosynthesis of a dolichylpyrophosphate-linked oligosaccharide before its transfer onto acceptor proteins1. The final seven steps occur in the lumen of the endoplasmic reticulum (ER) and require dolichylphosphate-activated mannose and glucose as donor substrates2. The responsible enzymes?ALG3, ALG9, ALG12, ALG6, ALG8 and ALG10?are glycosyltransferases of the C-superfamily (GT-Cs), which are loosely defined as containing membrane-spanning helices and processing an isoprenoid-linked carbohydrate donor substrate3,4. Here we present the cryo-electron microscopy structure of yeast ALG6 at 3.0 A resolution, which reveals a previously undescribed transmembrane protein fold. Comparison with reported GT-C structures suggests that GT-C enzymes contain a modular architecture with a conserved module and a variable module, each with distinct functional roles. We used synthetic analogues of dolichylphosphate-linked and dolichylpyrophosphate-linked sugars and enzymatic glycan extension to generate donor and acceptor substrates using purified enzymes of the ALG pathway to recapitulate the activity of ALG6 in vitro. A second cryo-electron microscopy structure of ALG6 bound to an analogue of dolichylphosphate-glucose at 3.9 A resolution revealed the active site of the enzyme. Functional analysis of ALG6 variants identified a catalytic aspartate residue that probably acts as a general base. This residue is conserved in the GT-C superfamily. Our results define the architecture of ER-luminal GT-C enzymes and provide a structural basis for understanding their catalytic mechanisms.
