A new series of dinuclear oxalato-bridged copper(II) and nickel(II) complexes derived from tridentate amines: [Cu2(Medpt)2(mu-C2O4)](ClO4)2 (1), [Cu2(pmedien)2(mu-C2O4)](ClO4)2 (2), [Cu2(DPA)2(mu-C2O4)(ClO4)2]¡¤2H2O (3), and [Ni2(Et2dien)2(mu-C2O4)(H2O)2](ClO4)2¡¤2H2O (4) (C2O42- = oxalate dianion, Medpt = 3,3?-diamino-N-methyldipropylmine, pmedien = N,N,N?,N??,N??-pentamethyldiethylenetriamine, DPA = di(2-pyridylmethyl)amine and Et2dien = N,N-diethyldiethylenetriamine) were synthesized and structurally characterized by X-ray crystallography. The spectral and structural characterizations of these complexes are reported. In this series, structures consist of the C2O42- bridging the two M(II) centers in a bis-bidentate bonding mode. The Cu2+ centers are coordinated to the tridentate amines Medpt or pmedien in distorted SP geometry in 1 and 2, respectively, with the ClO4- groups as counter ions. In the other two complexes, distorted octahedral geometries were achieved by the three nitrogen donors of the DPA and by an oxygen atom from coordinated perchlorate ion in 3 and by the Et2dien and one water molecule in 4.

A unified stereodivergent strategy for prostaglandin and isoprostanoid synthesis

Acetoxyfulvene surrended to asymmetric Diels-Alder cycloaddition, paving the way to the development of a unified strategy for the stereodivergent synthesis of both prostaglandins and isoprostanoids. In fact, the cycloadduct was subsequently converted to a common intermediate, which through two different stereoselective pathways afforded the two lactones 1 and 2, which are key building blocks in the synthesis of prostaglandins and isoprostanoids, respectively.

Crystal structure, Hirshfeld surface analysis and photocatalytic activities of a cobalt(III) complex based on acid and alkaline mixed ligands

A novel Co(III) complex [Co(chda)(nta)] (1) (chda = trans-(1R,2R)-1,2-cyclohexanediamine, H3nta = nitrilotriacetic acid) was synthesized based on chda and H3nta ligands at room temperature. Complex 1 was structurally identified by single-crystal X-ray diffraction, elemental analysis, FT-IR and Raman spectrum. Complex 1 was connected by the intermolecular N?H¡¤¡¤¡¤O hydrogen bonds to form a 2D supramolecular structure. The 3D Hirshfeld surface and 2D fingerprint plots were used to further study the intermolecular interactions of complex 1. The intermolecular O¡¤¡¤¡¤H and H¡¤¡¤¡¤H contacts were the most significant interactions in the crystal, which comprised 96.6% of the total Hirshfeld surface. In addition, complex 1 exhibited excellent photocatalytic activity for the removal of methylene blue under UV light. The possible photocatalytic mechanism and reaction kinetics were also discussed.

Enantioselective organocatalytic hantzsch synthesis of polyhydroquinolines

The four-component Hantzsch reaction provides access to pharmaceutically important dihydropyridines. To expand the utility of this method, we have developed a route under organocatalytic conditions with good yields and excellent ee’s. Through catalyst screening, we found that a BINOL-phosphoric acid allowed enantioselective synthesis of six-membered heterocycles with a variety of substitution patterns.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! Read on for other articles about 41661-47-6!, 75714-60-2

Sensing and capture of toxic and hazardous gases and vapors by metal-organic frameworks

Toxic and hazardous chemical species are ubiquitous, predominantly emitted by anthropogenic activities, and pose serious risks to human health and the environment. Thus, the sensing and subsequent capture of these chemicals, especially in the gas or vapor phase, are of extreme importance. To this end, metal-organic frameworks have attracted significant interest, as their high porosity and wide tunability make them ideal for both applications. These tailorable framework materials are particularly promising for the specific sensing and capture of targeted chemicals, as they can be designed to fit a diverse range of required conditions. This review will discuss the advantages of metal-organic frameworks in the sensing and capture of harmful gases and vapors, as well as principles and strategies guiding the design of these materials. Recent progress in the luminescent detection of aromatic and aliphatic volatile organic compounds, toxic gases, and chemical warfare agents will be summarized, and the adsorptive removal of fluorocarbons/chlorofluorocarbons, volatile radioactive species, toxic industrial gases and chemical warfare agents will be discussed.

Microwave-mediated synthesis of N-methyliminodiacetic acid (MIDA) boronates

A library of over 20, mainly aryl or heteroaryl, N-methyliminodiacetic acid (MIDA) boronates have been synthesised. A rapid microwave-mediated (MW) method (5-10 min) has been developed using polyethylene glycol 300 (PEG 300) as solvent. However, acetonitrile (MeCN) and dimethylformamide (DMF) were found to be alternative solvents, the latter especially for 2-substituted aryl boronic acids.

Formulation, physical characterization and in vitro evaluation of medicated chewing gum: Diethylcarbamazine citrate

Truncate Infections close by helminthes, or parasitic worms, affect more than two billion people worldwide. Looking at this situation an attempt has been made to formulate a novel drug delivery system known as medicated chewing gum containing masticatory gum base with pharmacologically active ingredient diethylcarbamazine citrate (used as a first-line agent for control and treatment of Lymphatic filariasis and for therapy of tropical pulmonary eosinophilia caused by Wuchereria bancrofti and Brugia malayi). Optimized formulations of medicated chewing gum with varying concentration of gum base were formulated. Evaluation parameter like Texture analysis (Hardness, Firmness and Springiness test) is carried out by Texture analyzer apparatus (TAXT plus). Improve essentials of casting & In-Vitro release profile of drug in saliva was obtained by formulation Fc3 (96.2%). Buccal absorption studies showed that 39.2% of drug absorbed within one minute when available to buccal mucosa at pH 5.5, commensurate with explain diethylcarbamazine citrate- medicated chewing gum (DEC-MCG) can be considered as better formulation for buccal drug delivery system in which drug is absorbed buccally and reaches the systemic circulation via jugular vein.

Multifunctional lanthanide coordination polymers

Lanthanide coordination polymers (Ln-CPs) have attracted explosive attention as an emerging type of multifunctional materials in the last decades. The establishment of the permanent porosity within Ln-CPs has enabled them to be a new class of materials for gas adsorption and separation. The unique luminescent properties, tunable emission colors, and various NIR emitting of luminescent Ln-CPs feature them as promising materials for solid-state light (SSL) applications in display devices, sensing and white-light emitting. Taking advantages of collaborative permanent porosities and unique luminescent properties, Ln-CPs are superior to other types of materials for their applications in luminescent chemical sensing, biomedical imaging as well as drug delivery monitoring and treatment. In this review, we focus on recent significant advances on this active research field and provide a comprehensive review on multifunctional Ln-CPs materials for gas adsorption and separation, tunable luminescence, chemical sensing, catalysis, and biomedical applications.
