Square pyramidal complexes [CuII(PFL)(bpa)Cl]{bullet operator}5H2O (1) and [CuII(LFL)(bpa)Cl]{bullet operator}5H2O (2) have been synthesized and characterized. Compounds were checked for their in-vitro antimicrobial activity against two Gram(+ ve) and three Gram(-ve) bacterial species. Intrinsic binding constant (Kb) of complexes with CT DNA were determined using absorption titration. Viscosity measurement suggests that complexes bind with CT DNA through partial nonclassical intercalative mode. Superoxide dismutase (SOD) like activity of the complexes was also compared with previously reported compounds.

Chemo-enzymatic cascade processes are invaluable due to their ability to rapidly construct high-value products from available feedstock chemicals. However, they have proven to be challenging because of the mutual inactivation of both catalysts. 74808-09-6, Name is (2R,3R,4S,5R,6R)-3,4,5-Tris(benzyloxy)-6-((benzyloxy)methyl)tetrahydro-2H-pyran-2-yl 2,2,2-trichloroacetimidate, molecular formula is C36H36Cl3NO6.

Reaction of O-benzyl-protected alpha-glycopyranosyl trichloroacetimidates 1 and the xylo analogues 7 with silyl enol ethers or allyltrimethylsilane as C-nucleophiles yields with zink chloride as catalyst mainly or exclusively alpha-C-glycosides (5a-alpha to 5h-alpha, 8b, c-alpha, 16-alpha, 18-alpha).For the reactions with trimethylsilyl cyanide to form alpha-C-glycosyl cyanides (10-alpha, 14-alpha, 15-alpha), trimethylsilyl trifluoromethanesulfonate was used as catalyst.Silyl enol ethers reacted with the 2-O-acetyl group of the O-acetylated alpha-glycosyl trichloroacetimidate 2 under formation of 1,3-dicarbonyl derivatives (9a, b). – Reaction of the alpha-glucopyranosylmethyl phenyl ketone 5a-alpha with Bredereck reagent and subsequently with hydrazine, acetamidine, or guanidine gives via intermediate anomerisation preferentially beta-C-nucleosides (21-beta, 24-beta, 25-beta).However, alpha-homo-C-nucleosides (26-alpha, 30-alpha to 32-alpha, 35-alpha, 38-alpha) are obtained from the corresponding reactions with alpha-glycopyranosylmethyl alkyl ketones 5c, d, e-alpha and 8c-alpha.For structural analysis these compounds were deprotected and acetylated.

The preparation and characterization of some copper(II)nitrito complexes with 2,2′-dipyridylamine (dipyam) are reported. The X-ray diffraction crystal structures of the [Cu(CH3COO)(dipyam)(ONO-O,O’)] (I) and [Cu(dipyam)(ONO-O,O’)(mu-ONO-O)]2·2CH3CN (II) complexes have been investigated. I consists of two crystallographically independent [Cu(acetato)(dipyam)-(ONO)] neutral complexes, self-assembled by cooperative N-H···O and C-H···O intermolecular interactions in supramolecular tetrameric units. Each copper atom exhibits a tetrahedrally-distorted square-basal geometry of the N2O2 donor set, with the second oxygen atoms of the cis-monodentate nitrito and of the acetato group weakly bound in nearly axial positions. II is a rare example of a dinuclear nitrito copper(II) derivative containing both cis-monodentate and O-bridging nitrito ligands. Each metal ion shows a distorted square-pyramidal coordination with the basal oxygen from the nitrito bridge occupying the axial site of the centrosymmetric complex. The H-bonding between the dipyam amino groups and acetonitrile molecules prevents the self-assembling of the dinuclear complexes. (C) 2000 Elsevier Science B.V.

Formula presented Intramolecular cycloadditions with high regio- and stereocontrol are important methods for the efficient assembly of complex molecular structures. Efficient routes to the synthesis of norbornadiene-tethered nitrile oxides have been developed, and their intramolecular 1,3-dipolar cycloadditions were studied. The cycloadditions occurred in good yields for a variety of substrates and were found to be highly regio- and stereoselective.

Redox catalysis has been broadly utilized in electrochemical synthesis due to its kinetic advantages over direct electrolysis. The appropriate choice can avoid electrode passivation, which strongly inhibit the efficient activation of substrates. 14215-68-0, Name is N-((2S,3R,4R,5R,6R)-2,4,5-Trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-3-yl)acetamide, molecular formula is C8H15NO6.

Glucosamine analogues are inhibitors of yeast hexokinase (HK); kinetic analysis with respect to glucose and ATP suggests a pseudo-substrate behaviour for these compounds. However, a spectroscopy study by 31P NMR indicates that they are not phosphorylated but that, in fact, they enhance the ATPase activity of HK; this result gives a further insight into the phosphorylation or ATP hydrolysis process in HK.

Among 18 oxometallic species, MoO2Cl2 was found to be the most reactive in catalytic thioglycosylation of O-acetylated glycosides with functionalized thiols in CH2Cl2, leading cleanly to 1,2-trans-thioglycosides with exclusive diastereocontrol. The new catalytic protocol is applicable to a monoglycoside building block and beta-(1?6)-S-linked-thiodisaccharide synthesis.

Five Cd(II) complexes with the anion of 5-NO2-salicylaldehydeH (5-NO2-saloH) in the absence or presence of the alpha-diimine 1,10-phenanthroline (phen), 2,2?-dipyridylamine (dpamH), 2,2?-dipyridine (bipy), or 2,9-dimethyl-1,10-phenanthroline (neoc) were synthesized and characterized as [Cd(5-NO2-salo)2(CH3OH)2] (1), [Cd(5-NO2-salo)2(phen)]·2CH3OH·H2O (2), [Cd(5-NO2-salo)2(dpamH)] (3), [Cd3(5-NO2-salo)6(bipy)2] (4), and [Cd(5-NO2-salo)(neoc)(NO3)]2 (5). Based on spectroscopic results (IR, UV, NMR), elemental analysis and conductivity measurements an octahedral geometry around cadmium metal ion is suggested, with the 5-NO2-salicylaldehyde ligand having different coordination modes. The structures determined by X-ray crystallography verified neutral mononuclear 1-3 and trinuclear 4. Simultaneous TG/DTG-DTA technique was used to analyze the thermal behavior of 1, 2, and 3. The complexes bind tightly to calf-thymus DNA mainly by intercalation, as concluded by DNA viscosity measurements and exhibit significant displacement of EB from the EB-DNA complex.

Chemistry can be defined as the study of matter and the changes it undergoes. You’ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology. 14215-68-0, Name is N-((2S,3R,4R,5R,6R)-2,4,5-Trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-3-yl)acetamide, molecular formula is C8H15NO6.

N(OMe)-linked disaccharide analogues, isosteric to the corresponding natural disaccharides, have been synthesized by chemoselective assembly of unprotected natural monosaccharides with methyl 6-deoxy-6-methoxyamino-alpha -D-glucopyranoside in an aqueous environment. The coupling reactions were found to be chemo- and stereoselective affording beta-(1?6) disaccharide mimics when using Glc and GlcNAc; in the case of Gal, the beta-anomer was prevalent (beta:alpha = 7:1). An iterative method for the synthesis of linear N(OMe) oligosaccharide analogues was demonstrated, based on the use of an unprotected monosaccharide building block in which an oxime functionality at C-6 is converted during the synthesis into the corresponding methoxyamino group. The conformational analysis of these compounds was carried out by using NMR spectroscopy, ab initio, molecular mechanics, and molecular dynamics methods. Optimized geometries and energies of fourteen conformers for each compound have been calculated at the B3LYP/631G* level. Predicted conformational equilibria were compared with the results based on NMR experiments and good agreement was found. It appears that N(OMe)-linked disaccharide analogues exhibit a slightly different conformational behavior to their parent natural disaccharides.
