Influence of a halide ion on ribbons of water pentamer

Reactions of CuF2, CuCl2 ? 2H2O and CuBr2 with 2,2?-dipyridylamine (HDPA) in water at room temperature using Cu:HDPA = 2:1 mol yield [Cu(HDPA)(H2O) 2F]F ? 3H2O (1), Cu(HDPA)Cl2 (2) and Cu(HDPA)Br2 (3) respectively. The structures of 2 and 3 are isostructural in spacegroup C2 with cell dimensions; for 2, a = 14.702(8), b = 7.726(2), c = 4.829(6) A, beta = 96.68(8) and for 3, a = 14.2934(8), b = 7.9057(6), c = 5.1982(5) A, beta = 94.049(7). In the X-ray crystal structure, the complex 1 is found to contain tapes of water pentamers. Our DFT calculations at the B3LYP/LanL2DZ level show that the reaction Cu(HDPA)X2 + 2H2O = [Cu(HDPA)(H 2O)2X]X is most exothermic in the gas phase when X – = F-, i.e., the tendency of water uptake is maximum for Cu(HDPA)F2. It seems that the exothermicities of the aquations of Cu(HDPA)Cl2 and Cu(HDPA)Br2 are not sufficient to stabilise the type of ribbons of water observed in 1 and consequently water is eschewed when X- = Cl- or Br-. Cu(2,2?-dipyridylamine)X2 takes up water to produce ribbons of water pentamer, as shown in the accompanied picture (red: O atom of a solvent water molecule), only when X- is F- but not when it Cl- or Br-. The results are rationalised by means of DFT calculations at the B3LYP/LanL2DZ level. [Figure not available: see fulltext.]

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: (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, you can also check out more blogs about499-40-1

Synthesis of Densely Functionalized Pyrimidouracils by Nickel(II)-Catalyzed Isocyanide Insertion

A robust nickel-catalyzed oxidative isocyanide insertion/C-H amination by reaction of readily available N-uracil-amidines with isocyanides affording polysubstituted pyrimidouracils has been reported. The reaction proceeds in moderate to quantitative yield, under mild conditions (i.e., green solvent, air atmosphere, moderate temperature). The broad range of structurally diverse isocyanides and N-uracil-amidines that are tolerated make this method an interesting alternative to the currently available procedures toward pyrimidouracils.

Immobilisation of eta3-allyldicarbonyl complexes of Mo II with bidentate nitrogen ligands within aluminium-pillared clays

Molybdenum(II) complexes [MoX(CO)2(eta3-allyl) (CH3CN)2] (X = Cl or Br) were encapsulated in an aluminium-pillared natural clay or a porous clay heterostructure and allowed to react with bidentate diimine ligands. All the materials obtained were characterised by several solid-state techniques. Powder XRD, and 27Al and 29Si MAS NMR were used to investigate the integrity of the pillared clay during the modification treatments. 13C CP MAS NMR, FTIR, elemental analyses and low-temperature nitrogen adsorption showed that the immobilisation of the precursor complexes was successful as well as the in situ ligand-substitution reaction. The new complex [MoBr(CO)2(eta 3-allyl)(2-aminodipyridyl)] was characterised by single-crystal X-ray diffraction and spectroscopic techniques, and NMR studies were used to investigate its fluxional behaviour in solution. The prepared materials are active for the oxidation of cis-cyclooctene using tert-butyl hydroperoxide as oxidant, though the activity of the isolated complexes is higher. Wiley-VCH Verlag GmbH & Co.

Active site loop conformation regulates promiscuous activity in a lactonase from Geobacillus kaustophilus HTA426

Enzyme promiscuity is a prerequisite for fast divergent evolution of biocatalysts. A phosphotriesterase-like lactonase (PLL) from Geobacillus kaustophilus HTA426 (GkaP) exhibits main lactonase and promiscuous phosphotriesterase activities. To understand its catalytic and evolutionary mechanisms, we investigated a “hot spot” in the active site by saturation mutagenesis as well as X-ray crystallographic analyses. We found that position 99 in the active site was involved in substrate discrimination. One mutant, Y99L, exhibited 11-fold improvement over wild-type in reactivity (kcat/Km) toward the phosphotriesterase substrate ethyl-paraoxon, but showed 15-fold decrease toward the lactonase substrate delta-decanolactone, resulting in a 157-fold inversion of the substrate specificity. Structural analysis of Y99L revealed that the mutation causes a ?6.6 A outward shift of adjacent loop 7, which may cause increased flexibility of the active site and facilitate accommodation and/or catalysis of organophosphate substrate. This study provides for the PLL family an example of how the evolutionary route from promiscuity to specificity can derive from very few mutations, which promotes alteration in the conformational adjustment of the active site loops, in turn draws the capacity of substrate binding and activity.

Rationally Designed Semisynthetic Natural Product Analogues for Stabilization of 14-3-3 Protein?Protein Interactions

The natural product family of fusicoccanes are stabilizers of 14-3-3 mediated protein?protein interactions (PPIs), some of which possess antitumor activity. In this study, the first use of molecular dynamics (MD) to rationally design PPI stabilizers with increased potency is presented. Synthesis of a focused library, with subsequent characterization by fluorescence polarization, mutational studies, and X-ray crystallography confirmed the power of the MD-based design approach, revealing the potential for an additional hydrogen bond with the 14-3-3 protein to lead to significantly increased potency. Additionally, these compounds exert their action in a cellular environment with increased potency. The newly found polar interaction could provide an anchoring point for new small-molecule PPI stabilizers. These results facilitate the development of fusicoccanes towards drugs or tool compounds, as well as allowing the study of the fundamental principles behind PPI stabilization.

Why Is Direct Glycosylation with N-Acetylglucosamine Donors Such a Poor Reaction and What Can Be Done about It?

The monosaccharide N-acetyl-d-glucosamine (GlcNAc) is an abundant building block in naturally occurring oligosaccharides, but its incorporation by chemical glycosylation is challenging since direct reactions are low yielding. This issue, generally agreed upon to be caused by an intermediate 1,2-oxazoline, is often bypassed by introducing extra synthetic steps to avoid the presence of the NHAc functional group during glycosylation. The present paper describes new fundamental mechanistic insights into the inherent challenges of performing direct glycosylation with GlcNAc. These results show that controlling the balance of oxazoline formation and glycosylation is key to achieving acceptable chemical yields. By applying this line of reasoning to direct glycosylation with a traditional thioglycoside donor of GlcNAc, which otherwise affords poor glycosylation yields, one may obtain useful glycosylation results.

Direct Synthesis of 3-Acylindoles through Rhodium(III)-Catalyzed Annulation of N-Phenylamidines with alpha-Cl Ketones

In the present study, a novel synthetic strategy to directly produce versatile 3-acylindoles through Rh(III)-catalyzed C-H activation and annulation cascade of N-phenylamidines with alpha-Cl ketones was developed, in which alpha-Cl ketones serve as unusual one-carbon (sp3) synthons. This strategy features high regioselectivity, efficiency, wide substrate tolerance, and mild reaction conditions, which further underscore its synthetic utility in drug molecule synthesis.
