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.

The reactant in an enzyme-catalyzed reaction is called a substrate. Enzyme inhibitors cause a decrease in the reaction rate of an enzyme-catalyzed reaction.I hope my blog about 74808-09-6 is helpful to your research., Product Details of 74808-09-6

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.

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.Formula: C36H36Cl3NO6, you can also check out more blogs about74808-09-6

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.

Glycosylidene carbenes. Part 14. Glycosidation of partially protected galactopyranose-, glucopyranose-, and mannopyranose-derived vicinal diols

The relation between H-bonding in diequatorial trans-1,2 and axial,equatorial cis-1,2-diols and the regioselectivity of glycosidation by the diazirine 1 was examined. H-Bonds were assigned on the basis of FT-IR and 1H-NMR spectra (Fig. 1). Glycosidation by 1 of the gluco-configurated diequatorial trans-2,3-diols 4-7 yielded the mono-glucosylated products 16/17/20/21 (69-89%); 1,2-/1,3-linked products 37-46:63-54), 24/25/28/29 (60-63%; 1,2-/1,3,-linked products 46-51:54-49), 32-35 (69-94%; 1,2-/1,3-linked products 45-52:55-48), and 36/37/40/41 (59-63%; 1,2-/1,3-linked products 52-59:48-41), respectively (Scheme 1, Table 3). The disaccharides derived from 4, 5, and 7 were characterized as their acetates 18/19/22/23, 26/27/30/31, and 38/39/42/43, respectively. Glycosidation of the galacto-configurated diequatorial 2,3-diols 8 and 9 and the manno-configurated diequatorial 3,4-diol 10 by 1 (Scheme 2, Table 3) also proceeded in fair yields to give the disaccharides 44-47 (69-80%; 1,2-/1,3-linked products ca. 1:1), 48-51 (51-61%; 1,2-/1,3-linked products 54-56:56-54), and 56/57/60/61 (71-80%; 1,3-/1,4-linked products 49-54:51-46), respectively. The 1,3-linked disaccharides 56/57 derived from the diol 10 were characterized as the acetates 58/59. The regio- and stereoselectivities of the glycosidation by 1 were much better for the alpha-D-manno-configurated axial,equatorial cis-2,3-diol 11 and the galacto-configurated axial, equatorial cis-3,4-diol 13 (1,2-/1,3-linked disaccharides ca. 3:7 for 11 and 1,3,-/1,4-linked disaccharides ca. 4:1 for 13; Scheme 3, Table 4). The regio- and stereoselectivity for the beta-D-manno-configurated cis-2,3-diol 12 were, however, rather poor (1,2-/1,3-linked products 48:52). The 1,2-linked disaccharides 66/67 derived from 12 were characterized as the acetates 70/71. Koenigs-Knorr-type glycosidation of the cis-diols 11-13 by 2 or 3 proceeded with a similar regio- and a higher stereoselectivity (alpha-D > beta-D with the donor 2 and alpha-D < beta-D with the donor 3) than with 1, with the exception of 12 which did not react with 2. The regioselectivity of the glycosidations by 1 agrees fully with the H-bonding scheme of the diols and with the hypothesis that the intermediate carbene is preferentially protonated by the most weakly H-bonded OH group. The regioselectivity of the glycosidation by 2 and by 3 is determined by a higher reactivity of the equatorial OH groups and by H-bonding. Several H-bonded and equilibrating isomers of a given diol may intervene in the glycosidation by 1, or 2 and 3, resulting in the same regioselectivity. The low nucleophilicity of 12 and the low degree of regioselectivity in its reaction with 3 show that stereoelectronic effects may also profoundly influence the nucleophilicity of OH groups.
