Photoinduced glycosylation of alcohols with alpha-glucosyl trichloroacetimidates, using aryl urea and thioureas as organo photoacids, was examined under long wavelength UV (ultraviolet) irradiation. The results show, for the first time, that such glycosylations proceed effectively to give the corresponding glycosides in high yields. In addition, high beta-stereoselectivity was obtained under high concentration conditions, whereas high alpha-stereoselectivity was realized under low concentration conditions.

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.Product Details of 74808-09-6, you can also check out more blogs about74808-09-6

Preparation of three positional isomers of diglucosyl-cyclomaltohexaose

Three positional isomers of diglucosyl-cyclomaltohexaose (diglucosyl-cG6) were chemically synthesized via 61,62-, 61,63-, and 61,64-di-O-(tert-butyldimethylsilyl)-cG6s (1, 2, and 3) prepared regiospecifically. Glucosylation of bis(2,3-di-O-acetyl)tetrakis(2,3,6-tri-O-acetyl)-cG6s obtained from the three regioisomeric compounds 1, 2, and 3 with 2,3,4,6-tetra-O-benzyl-1-O-trichloroacetimidoyl-alpha-D-glucopyranose, followed by debenzylation and then deacetylation, afforded 61,62-, 61,63-, and 61,64-di-O-(alpha-D-glucopyranosyl)-cG6s (10, 11, and 12) together with configurational isomers. The desired compounds 10, 11, and 12 containing two (1 ? 6)-alpha-linkages were isolated from the mixtures of their configurational isomers by high performance liquid chromatography. The three diglucosyl-cG6s synthesized chemically were used as authentic samples to identify the components in a mixture of diglucosyl-cG6s produced by an enzymatic process.

Glycosylimidates, 8. – Synthesis of 1-Thioglycosides

As expected, the reactive acetyl-protected O-(alpha-D-glucopyranosyl) trichloroacetimidate 3 reacts with S-nucleophiles and trifluoroborane-ether as catalyst to yield exclusively 1-thio-beta-D-glucopyranosides with inversion of the configuration.The corresponding benzyl-protected alpha-trichloroacetimidate 4 affords with retention of the configuration alkyl 1-thio-alpha-D-glucopyranosides.The importance of alkyl 1-thio-beta-D-galactopyranosides in enzyme induction was reason to apply this convenient and efficient glycosyl-transfer reaction to the synthesis of isopropyl 1-thio-beta-D-galactopyranoside (12a) and the sodium salt of 1-thio-beta-D-galactopyranose (12b), respectively.

Glucose uptake enhancing activity of puerarin and the role of C-glucoside suggested from activity of related compounds

Chemical treatment of diabetes mellitus is widely studied and controlling of blood glucose level is the main course of therapy. In type 2 diabetes mellitus, insulin resistance is the major problem. An isoflavone C-glucoside, puerarin (1), is known to enhance glucose uptake into the insulin sensitive cell and is thought to be a candidate for treatment of diabetes mellitus. We synthesized 1 and several derivatives to apply for the structure-activity relationship study. The result against 3T3-L1 adipocyte indicated that the C-glucoside part of 1 is unconcerned in its activity when tested in vitro and the main structure responsible for its activity was the isoflavone moiety.

6-O-benzyl- and 6-O-silyl-N-acetyl-2-amino-2-N,3-O-carbonyl-2- deoxyglucosides: Effective glycosyl acceptors in the glucosamine 4-OH series. Effect of anomeric stereochemistry on the removal of the oxazolidinone group

(Chemical Equation Presented) The 4-OH groups of both alpha- and beta-methyl glycosides of N-acetylglucosamine, protected with an oxazolidinone spanning the nitrogen and O-3, and bearing benzyl or silyl protection on O-6, show excellent reactivity as acceptors in couplings to a range of glycosyl donors. The enhanced reactivity of these acceptors is attributed in part to the tied back nature of the oxazolidinone, which reduces hindrance around the nucleophilic oxygen. The N-acetyloxazolidinone function also reduces the tendency seen in simple N-acetylglucosamines toward amide glycosylation, and removes the possibility of problematic hydrogen bonding networks. In the beta-, but not the alpha-, series selective hydrolysis of the N-acetyloxazolidinone directly to the N-acetylglucosamine was possible with barium hydroxide, a feature attributed to chelate formation between the acetamide carbonyl group and the glycosidic oxygen in the beta-series.

The Glc2Man2-fragment of the N-glycan precursor – A novel ligand for the glycan-binding protein malectin?

The Glcalpha(1?3)Glcalpha(1?3)Manalpha(1?2)Man tetrasaccharide (Glc2Man2-fragment), a substructure of the natural N-glycan precursor, was synthesized. The interaction of this fragment with the protein malectin, a carbohydrate binding protein localized in the endoplasmatic reticulum, was investigated by 1H15N HSQC experiments and isothermal calorimetry. The chemical shift perturbations of nuclei in the protein’s backbone caused by the binding of the Glc 2Man2-fragment to malectin suggest a binding mode like the known ligand nigerose.
