A blue photoluminescent [Zn(L)(CN)2] (L = 2,2?-dipyridylamine) material with a supramolecular one-dimensional chain structure

A novel blue luminescent [Zn(L)(CN)2] complex (L = 2,2?-dipyridylamine) is synthesized and characterized by an X-ray diffraction study; the crystal packing in the Zn complex reveals that the molecules self-assemble by intermolecular hydrogen bonds [N-H…N?C distance = 2.965(7) A] and face-to-face pi=pi aromatic stacking interactions to form two-dimensional sheets.

Ruthenium complexes with N-functionalized secondary amino ligands: a new class of catalysts toward efficient hydrogenation of esters

A series of ruthenium complexes (o-PPh2C6H4NHR)2RuCl2 (R = Me, 3; Et, 4; CH2Ph, 5) and (o-PPh2C6H4NH2)[(CH2NHR)2]RuCl2 (R = Me, 7; Et, 8; iPr, 9) modulated with mono-N-functionalized secondary amino ligands were synthesized and demonstrated as efficient catalysts in the hydrogenation of esters into alcohols. The catalytic performances of these new complexes are much better than their corresponding primary amino ligand-constituted complexes (o-PPh2C6H4NH2)2RuCl2 (2) and (o-PPh2C6H4NH2)[(CH2NH2)2]RuCl2 (6). The significant improvement is attributed to the increased electron density of the secondary amino ligand in comparison with that of the primary amino ligand.

Discovery, synthesis and characterization of a series of (1-alkyl-3-methyl-1H-pyrazol-5-yl)-2-(5-aryl-2H-tetrazol-2-yl)acetamides as novel GIRK1/2 potassium channel activators

The present study describes the discovery and characterization of a series of 5-aryl-2H-tetrazol-3-ylacetamides as G protein-gated inwardly-rectifying potassium (GIRK) channels activators. Working from an initial hit discovered during a high-throughput screening campaign, we identified a tetrazole scaffold that shifts away from the previously reported urea-based scaffolds while remaining effective GIRK1/2 channel activators. In addition, we evaluated the compounds in Tier 1 DMPK assays and have identified a (3-methyl-1H-pyrazol-1-yl)tetrahydrothiophene-1,1-dioxide head group that imparts interesting and unexpected microsomal stability compared to previously-reported pyrazole head groups.

Practical preparation of lacto-N-biose I, a candidate for the bifidus factor in human milk

A one-pot enzymatic reaction to produce lacto-N-biose I (LNB), which is supposed to represent the bifidus factor in human milk oligosaccharides, was demonstrated. Approximately 500mM of LNB was generated in 10-liter of reaction mixture initially containing 660 mM of sucrose and 600mM of GlcNAc by the concurrent actions of four enzymes, sucrose phosphorylase, UDP-glucose – hexose-1-phospate uridylyltransferase, UDP-glucose 4-epimerase, and lacto-N-biose phosphorylase, in the presence of UDP-Glc and phosphate, indicating a reaction yield of 83%. LNB was isolated from the mixture by crystallization after yeast treatment. Finally, 1.4 kg of LNB of 99.6% purity was recovered after recrystallization.

Acid-Catalyzed Hydrolyses of 2-Alkoxytetrahydropyrans: Evidence for the Changeover from an A1 to an ASE2 Mechanism

Kinetics of the acid-catalyzed hydrolyses of 2-ethoxy-, 2-methoxy-, 2-(2-methoxyethoxy)-, 2-(2-chloroethoxy)-, 2-(propargyloxy)-, and 2-(2,2,2-trifluoroethoxy)tetrahydropyran have been studied in aqueous acidic solutions.The hydrolysis of 2-(2,2,2-trifluoroethoxy)tetrahydropyran occurs by an ASE2 mechanism and exhibits the requisite general acid catalysis.While this mechanism cannot be strictly excluded for the hydrolysis of 2-ethoxytetrahydropyran, the lack of observation of general acid catalysis and the manner in which enthalpies and entropies of activation change as the 2-alkoxy group is changed strongly suggest an A1 mechanism.A rationale is presented for using entropies of activation as an indication of changeover from an A1 to an ASE2 mechanism, based on the tetrahydropyran series (where such a changeover appears to occur) and on the benzaldehyde series (where hydrolyses occur by an ASE2-like mechanism).It is observed that in order for a physical organic model to closely resemble the hydrolysis of a natural substrate at the active site of an enzyme (e.g., lysozyme), the leaving group must contain electronegative groups: aryloxy, 2,2,2-trifluoroethoxy, and 2-propargyloxy all seem adequate.This structural feature is much more important than inherent reactivity; thus 2-(2,2,2-trifluoroethoxy)tetrahydropyran is a better reaction model than methyl glucosides.

Synthesis of labelled terminal [14C]-acetylenes

There are several literature methods for conversion of 14C precursors into [14C]-acetylenes, and a number of these involve elaboration of [14C]-aldehydes into a terminal acetylenes. One method that involves mild conditions, and in our experience is high yielding and tolerant of a range of functional groups uses the Ohira-Bestmann reagent to effect this transformation. This document briefly describes some of the different methods that have been used for the preparation of [ 14C]-acetylenes and discusses two worked examples, the synthesis of [5-14C]-hex-5-ynoic acid and [benzene-(U)-14C]-7- methoxybenzofuran, both of which involve Ohira-Bestmann chemistry being used for the preparation of terminal [14C]-acetylenes.

The effect of alkyl chain tethers on the kinetics and mechanistic behaviour of bifunctional dinuclear platinum(II) complexes bearing N, N ?-dipyridylamine ligands

In the current paper, we report the kinetics of bifunctional dinuclear platinum(ii) complexes viz., 1,2-N,N?-di-(2,2-dipyridylamine)ethanetetraaquaplatinum(ii), PtL2, 1,3-N,N?-di-(2,2-dipyridylamine)propanetetraaquaplatinum(ii), PtL3, 1,4-N,N?-di-(2,2-dipyridylamine)butanetetraaquaplatinum(ii), PtL4, 1,5-N,N?-di-(2,2-dipyridylamine)pentanetetraaquaplatinum(ii), PtL5 and 1,6-N,N?-di-(2,2-dipyridylamine)hexanetetraaquaplatinum(ii), PtL6. The substitution reactions were carried out on tetraaqua complexes with thiourea nucleophiles under pseudo-first-order conditions as a function of nucleophile concentration and temperature by stopped-flow and UV-vis spectrophotometric techniques. An experimental study was conducted with the aim of determining the influence of alkyl chains on the steric and electronic structure of dinuclear platinum(ii) complexes. The reactivity of these complexes was dependent on the length of the alkyl spacer. The results obtained herein demonstrate the intriguing odd-even effects induced by the alkyl chain on the complexes. Artificial constraints imposed by the alkyl chain significantly affect their conformational structure to be either synperiplanar (syn-) or antiperiplanar (anti-) characterized by the odd and even effect. The kinetic, mechanistic and conformational behaviour was influenced by the size of the alkyl chain in accordance with odd-even alterations of the spacer. Computational modeling using density functional theory (DFT) calculations supplemented experimental findings that structural features and the reactivity pattern of these organometallic complexes are governed by both steric and electronic effects arising from the flexibility and inductive nature of the alkyl spacer. The strong sigma-donicity of longer alkyl chains favours sufficient accumulation of electron density at the metal centre and stabilizes a 14-electron intermediate. The study shows the HOMO-LUMO energy (DeltaE) is affected by the length of the spacer. Kinetic and DFT data indicate electron donation by the alkyl spacer. The low positive values of enthalpy of activation and significantly large negative values of entropy of activation indicate an associative mechanism of substitution.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 499-40-1 is helpful to your research., Synthetic Route of 499-40-1
