C-glycosides are important compounds as they are used as bioactive molecules and building blocks. We have developed methods to concisely synthesize C-glycosides from unprotected 2-N-acyl-aldohexoses and unactivated ketones; we designed aldol-condensation-oxa-Michael addition reactions catalyzed by amine-based catalysts using additives. Depending on the conditions used, C-glycosides were stereoselectively obtained. Our methods allowed the C-C bond formations at the anomeric centers of unprotected carbohydrates under mild conditions to lead the C-glycosides in atom- and step-economical ways.

Electric Literature of 499-40-1. Let¡¯s face it, organic chemistry can seem difficult to learn. Especially from a beginner¡¯s point of view. Like 499-40-1, Name is (2R,3S,4R,5R)-2,3,4,5-Tetrahydroxy-6-(((2S,3R,4S,5S,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-2-yl)oxy)hexanal. In a document type is Article, introducing its new discovery.

Cobalt(II) complexes with a series of non-steroidal anti-inflammatory drugs (diflunisal, flufenamic acid, mefenamic acid and niflumic acid) in the presence of nitrogen-(2,2?-bipyridylamine, 2,2?-bipyridine, 1,10-phenanthroline) and/or oxygen-donor ligands (methanol) have been synthesized and characterized with physicochemical and spectroscopic techniques. The deprotonated NSAID ligands are coordinated to Co(II) ion through their carboxylato groups in diverse binding modes. The crystal structures of complexes [Co(diflunisal-O)2(methanol)4], [Co(niflumato-O)2(methanol)4], [Co(flufenamato-O,O’)2(2,2?-bipyridylamine)], [Co(mefenamato-O,O’)2(2,2?-bipyridylamine)] and [Co3(flufenamato-O,O’)4(flufenamato-O,O,O’)2(2,2?-bipyridine)2] have been determined by X-ray crystallography. The interaction of the complexes with serum albumins was studied by fluorescence emission spectroscopy and the albumin-binding constants were determined. The ability of the complexes to scavenge 1,1-diphenyl-picrylhydrazyl, 2,2?-azinobis(3-ethylbenzothiazoline-6-sulfonic acid) and hydroxyl radicals was investigated and the complexes were more active than the corresponding free drugs. Spectroscopic (UV and fluorescence), electrochemical (cyclic voltammetry) and physicochemical (viscosity measurements) techniques were employed in order to study the binding mode of the complexes to calf-thymus (CT) DNA and to calculate the corresponding binding constants; for all complexes, intercalation was suggested as the most possible DNA-binding mode.

beta-Galactosidase activities from the recombinant thermophilic CLONEZYME(TM) glycosidase library were screened at 70C for catalysis of a transgalactosylation from o-nitrophenyl-beta-galactopyranoside to N-acetylglucosamine. Three thermophilic glycosidases (Gly001-06, -07 and -09) were found to produce predominantly the beta(1-4)-linked isomer, Gal beta(1-4)GlcNAc with up to 61% yield and less than 10% of the hydrolysis side reaction product. Thus, commercial recombinant thermophilic enzyme libraries constitute a novel class of biocatalysts for preparative organic synthesis.

The commercially available 2,2?-dipyridylamine was used as a supporting ligand in the palladium-catalyzed Sonogashira cross-coupling reaction. The reactions between aryl iodides and terminal alkynes with different steric hindrance can be efficiently performed in the absence of copper in neat water at room temperature. The superior catalytic performance of the catalytic system was attributed to water solubility of the palladium 2,2?- dipyridylamine complex. Palladium nanoparticles with small size and narrow size distribution were formed after the cross-coupling reaction.
