A series of novel thiazolo[4,5-d]pyrimidin-7(6H)-ones (3aa-3eq) were designed, synthesized, and evaluated as the type I positive allosteric modulators of human alpha 7 nAChR expressed in Xenopus ooctyes by a two-electrode voltage clamp. The structure-activity relationship analysis identified the compound 3ea as a potent and efficacious PAM with the maximum activation effect of the alpha 7 current of over 1633% in the presence of acetylcholine (100 mu M) and an EC50 = 1.26 mu M. It is highly specific to alpha 7 nAChR over other subtypes of nAChR, 5-HT3A, NMDA, and GABA(A) receptors. Compound 3ea showed an elimination half-life of 10.8 +/- 1.5 h for 3 mg/kg, i.v., and 7.4 +/- 1.1 h for 60 mg/kg, i.g. in rat. It also exhibited sufficient blood-brain barrier penetration with no significant effect on hERG channel. Most importantly, compound 3ea dose-dependently (0.1-1 mg/kg, i.p.) reversed the prepulse inhibition deficit induced by MK-801 in the mouse schizophrenia model. X

A series of imidazolium-based palladate precatalysts has been synthesized and the catalytic activity of these air- and moisture-stable complexes evaluated as a function of the nature of the imidazolium counterion. These precatalysts can be converted under catalytic conditions to Pd-NHC species capable of enabling the Buchwald-Hartwig aryl amination and the alpha-arylation of ketones. Both reactions can be carried out efficiently under very mild operating conditions. The effectiveness of the protocol was tested on functionality-laden substrates.

Chloroaluminate ionic liquids (ILs) have been immensely used as homogeneous catalyst in Friedel-Crafts reaction. We have recently synthesized chloroaluminate ILs by reacting aluminium chloride with a hydrophobic neutral ligand i.e. tributylamine (TBA:AlCl3). The current study elaborates on the investigations of the composition of the ionic liquids at various stages of their formation. The ionic liquids were synthesized using various mole ratios of tributyl amine and aluminium chloride in range of 1:1 to 1:2.3, in presence of an aromatic solvent in a one pot reaction. Various characterization techniques like Mass spectrometry, Al-27 Nuclear Magnetic Resonance, P-31 Nuclear Magnetic Resonance and Fourier Transform Infrared spectroscopy were used to elucidate the formation of various moieties of the TBA:AlCl3 Ionic Liquid. This study also elaborates on the investigations of the cationic and anionic moieties and their structure-property relationship for various applications. Various Friedel-Crafts reaction of industrial importance were performed using the ionic liquid having (Al2Cl7)(-) moiety to assess its performance and compared with conventional processes. The synthesized products were characterised by sophisticated analytical techniques like H-1 NMR, C-13 NMR, FTIR, GC-MS, GC-FID, to name a few. This class of ionic liquids also have importance in various electrochemical applications like aluminium deposition and aluminium batteries. (C) 2020 Elsevier B.V. All rights reserved.

Here, we report a class of ligands based on oxalohydrazide cores and N-amino pyrrole and N-amino indole units that generates long-lived copper catalysts for couplings that form the C-O bonds in biaryl ethers. These Cu-catalyzed coupling of phenols with aryl bromides occurred with turnovers up to 8000, a value which is nearly two orders of magnitude higher than those of prior couplings to form biaryl ethers and nearly an order of magnitude higher than those of any prior copper-catalyzed coupling of aryl bromides and chlorides. This ligand also led to copper systems that catalyze the coupling of aryl chlorides with phenols and the coupling of aryl bromides and iodides with primary benzylic and aliphatic alcohols. A wide variety of functional groups including nitriles, halides, ethers, ketones, amines, esters, amides, vinylarenes, alcohols and boronic acid esters were tolerated, and reactions occurred with aryl bromides in pharmaceutically related structures.

Ylide-functionalized phosphine ligands (YPhos) were rationally designed to fit the requirements of Buchwald-Hartwig aminations at room temperature. This ligand class combines a strong electron-donating ability comparable to NHC ligands with high steric demand similar to biaryl phosphines. The active Pd species are stabilized by agostic C-H center dot center dot center dot Pd rather than by Pd-arene interactions. The practical advantage of YPhos ligands arises from their easy and scalable synthesis from widely available, inexpensive starting materials. Benchmark studies showed that YPhos-Pd complexes are superior to the best-known phosphine ligands in room-temperature aminations of aryl chlorides. The utility of the catalysts was demonstrated by the synthesis of various arylamines in high yields within short reaction times.

We report a highly efficient ortho-selective electrophilic chlorination of phenols utilizing a Lewis basic selenoether catalyst. The selenoether catalyst resulted in comparable selectivities to our previously reported bis-thiourea ortho-selective catalyst, with a catalyst loading as low as 1%. The new catalytic system also allowed us to extend this chemistry to obtain excellent ortho-selectivities for unprotected anilines. The selectivities of this reaction are up to >20:1 ortho/para, while the innate selectivities for phenols and anilines are approximately 1:4 ortho/para. A series of preliminary studies revealed that the substrates require a hydrogen-bonding moiety for selectivity.

Herein, we report the development of aryl halide-dependent chemoselective reactions, viz., the Buchwald-Hartwig type coupling reaction of an aryl iodide with an arylboronic acid and an aryl amine in the presence of a heterogeneous and reusable nickel catalyst and the Suzuki-Miyaura type coupling of an aryl chloride under similar conditions. Control experiments revealed that the presence of stoichiometric amounts of the phenylboronic acid/ester and aryl amine are essential for both reactions. NMR and XAFS studies suggested the formation of a boron-amine ate complex.

An article Novel mixture descriptors for the development of quantitative structure-property relationship models for the boiling points of binary azeotropic mixtures WOS:000506712600055 published article about GENETIC ALGORITHM; DISTILLATION; PREDICTION; QSAR; EQUATION; TREE in [Faramarzi, Zohreh; Zare-Shahabadi, Vahid; Jahromi, Hossein Jalali] Islamic Azad Univ, Dept Chem, Mahshahr Branch, Mahshahr, Iran; [Abbasitabar, Fatemeh] Islamic Azad Univ, Dept Chem, Marvdasht Branch, Marvdasht, Iran in 2019.0, Cited 38.0.

Binary azeotropes, which contain two chemical constituents, are very common in industry. Understanding azeotropic properties is crucial for effectively separating binary azeotropes. Experimental and theoretical approaches such as ab initio have been used to estimate mixture properties but they are costly and time-consuming. The quantitative structure-property relationship (QSPR) model is a viable alternative approach. The most challenging problem in the QSPR study of mixtures is the computation of numerical descriptors to characterize a mixture. In this study, a series of twenty-two formulas were proposed to derive mixture descriptors from the molecular descriptors of the individual pure compounds. The derived mixture descriptors were employed to establish QSPR models to predict the boiling point of binary azeotropic mixtures. The QSPR model developed was found to be the best with R-train(ing)2 and R-test(2) of 0.92 and 0.90 on the basis of a novel proposed formula, in which some coefficients related to the potential energy contribution were used. Mean absolute errors (MAEs) associated with training and test sets were computed as 9.90 and 10.61, respectively. Twelve out of the twenty-two mixture descriptors resulted in the QSPR models with reasonable statistical qualities and, therefore, were taken into account in the production of an ensemble model via a simple averaging strategy. This caused to improve statistical quality of the final QSPR model. (C) 2019 Published by Elsevier B.V.

Background The side reactions of dehalogenation or C-N coupling tend to occur when halogenated aromatic amines are prepared by catalytic hydrogenation reduction of halogenated aromatic nitro compounds. In this paper, we prepared the sub-microspherical Fe3O4@PDA-Pd NPs catalyst apply it efficiently in the hydrogenation reduction of halogenated aromatic nitro compounds to prepare the halogenated aromatic amines under atmospheric pressure. The catalyst shows a high selectivity of greater than 96% and can effectively inhibit the occurrence of the side reactions of dehalogenation and C-N coupling. Results The optimum condition of the hydroreduction reaction is when tetrahydrofuran is used as solvent and the reaction happens at 50 degrees C for 5 h. The selectivity of the chlorinated aromatic amine and the fluorinated aromatic amine products exceed 99% and the yield exceeds 90%. Only a small amount of dehalogenated products and C-N coupling by-products were produced in the brominated aromatic compound and the iodinated aromatic compound. Conclusion We developed a promising method for preparing the superparamagnetic and strongly magnetic Fe3O4@PDA core-shell sub-microsphere-supported nano-palladium catalyst for catalyzing the hydrogenation reduction of halogenated aromatic nitro compounds. The halogenated aromatic amines were efficiently and highly selectively prepared under atmospheric pressure, with the side reactions of dehalogenation and C-N coupling effectively inhabited simultaneously.
