A new tridentate ligand (H3L) was prepared from the reaction of 6-formyl-2-(hydroxymethyl)-4-tert-butylphenol and 2-amino-4-nitrophenol. The ligand H3L and acetylacetone were treated with Er (NO3)(3)center dot 5H(2)O, which resulted in the formation of a pentanuclear coordination cluster [Er-5(LH)(4)(acac)(4)(mu(3)-O)(mu(3)-OH)(H2O)(2)](.)5H(2)O (1) (acac = acetylacetonate). Five Er (III) ions are arranged in a nonlinear fashion in 1. Complex 1 was utilized as a catalyst towards the selective synthesis of 1,2-disubstituted benzimidazole derivatives involving o-phenylenediamine and different aldehydes. Yields of 1,2-disubstituted benzimidazole derivatives were in the range of 66%-91%. This study demonstrates the first-ever approach to employ a homo- and pentanuclear lanthanide coordination cluster for catalyzing the synthesis of 1,2-disubstituted benzimidazoles.

Fragile cultural relics at underwater archaeological sites are difficult to preserve in situ over long time periods due to the effects of a complex and constantly changing surrounding environment. Thus, extracting the relics from water and preserving them in a controllable environment is of primary importance. In this paper, the technology of temporary reinforcement and extraction of underwater fragile relics with veratraldehyde followed by a process of secondary temporary reinforcement using polyethylene glycol (PEG) was studied. After investigating the melting temperature and permeability of PEGs with different molecular weights, we found that PEG-3000 is an excellent candidate as the secondary reinforcing agent for the extracted relics. In the laboratory, combined with veratraldehyde and polypropylene-fiber cloth as temporary underwater strengthening materials, and selected dispersed beaded jewelry and a broken three-dimensional crock as our research subject, we carried out an entire retrieval process-temporary stabilization and secondary temporary reinforcement, to systematically evaluate the technological aspects of safely excavating fragile underwater relics in the original state. After being extracted from water and subjected to secondary temporary reinforcement using PEG-3000, the beaded jewelry and broken crock retained their underwater shape and arrangement completely. The use of secondary reinforcing agent prevents the removal process of veratraldehyde and enclosed sediment from affecting the state of the relics.

In the present work three chromeno naphthyridine derivatives (CNs) have been synthesized using one pot multicomponent reaction of 2, 4-hydroxyacetophenone, aromatic aldehydes and malononitrile in water using silica gel as a catalyst. The simulated LDse values for the synthesized compounds are 340 mg/kg (CN-1), 1500 mg/kg (CN-2) and 800 mg/kg (CN-3) which suggest their non-toxic and eco-friendly nature The performance all the three compounds as corrosion inhibitors in 15% HCl on N80 has been analyzed via weight loss, electrochemical, surface characterization, and density functional theory (DFT) methods. Chromeno naphthyridine (CN-1) shows maximum inhibition efficiency of 98.3% at only 300 mg/L The measurement of EIS reveals the process of inhibition of corrosion is governed by control of charge transfer. The mixed nature of CNs adsorption is suggested by results of PDP. Langmuir model of adsorption shows the perfect fitting. Adsorption of CNs onto the metal surface was supported by MR. AFM, and UV-vis. Computational modelling using DFT data reveals that corrosion inhibition takes place by adsorption of both neutral and protonated forms on steel surface. Molecular dynamic simulation (MDS) suggests the parallel adsorption of CNs molecules both in neutral and protonated forms. (C) 2020 Elsevier B.V. All rights reserved.

One effective means to achieve inhibitor specificity for RAF kinases, an important family of cancer drug targets, has been to target the monomeric inactive state conformation of the kinase domain, which, unlike most other kinases, can accommodate sulfonamide-containing drugs such as vemurafenib and dabrafenib because of the presence of a unique pocket specific to inactive RAF kinases. We previously reported an alternate strategy whereby rigidification of a nonselective pyrazolo[3,4-d]pyrimidine-based inhibitor through ring closure afforded moderate but appreciable increases in selectivity for RAF kinases. Here, we show that a further application of the rigidification strategy to a different pyrazolopyrimidine-based scaffold dramatically improved selectivity for RAF kinases. Crystal structure analysis confirmed our inhibitor design hypothesis revealing that 21 engages an active-like state conformation of BRAF normally associated with poorly discriminating inhibitors. When screened against a panel of distinct cancer cell lines, the optimized inhibitor 21 primarily inhibited the proliferation of the expected BRAF(V600E)-harboring cell lines consistent with its kinome selectivity profile. These results suggest that rigidification could be a general and powerful strategy for enhancing inhibitor selectivity against protein kinases, which may open up therapeutic opportunities not afforded by other approaches.

A highly chemoselective transesterification of methyl (meth)acrylates catalyzed by sterically demanding 2,6-di-tert-butyl-4-methylphenol-derived NaOAr or Mg(OAr)(2) was developed. The desired transesterification proceeded without the undesired Michael additions under mild reaction conditions at 25 degrees C, and various primary and secondary alcohols, diols, triol, and tetraol on a scale of up to 10 mmol could provide the corresponding functionalized acrylates in high yields. Transition states were proposed based on monomeric and dimeric active species, and computational density functional theory calculations strongly supported high chemoselectivity to minimize undesired Michael additions.

An urgent yet challenging task is to overcome the limitations in substrate scope and regio- and chemoselectivity in the oxidative couplings between two arenes for the construction of unsymmetrical 2,2′-difunctional biaryls with diverse application requirements. In this work, a co-oxidant-free Rh(I)/Zn(NTf2)(2)/air catalytic system has been developed for dual chelation-assisted oxidative C-H/C-H cross-couplings between two anilines, between two phenols, and between phenols and anilines, which enables rapid assembly of rich libraries of 2,2′-bianilines, 2,2′-biphenols, and 2′-aminobiphenyl-2-ols. This protocol features air as the sole oxidant, complete regioselectivity, high chemoselectivity, low molar ratio of substrates (even 1:1), convenient operation, and scale-up synthesis. The established catalytic system is tolerant of the substrates having both electron-donating and electron-withdrawing substituents at different positions of the aryl ring. This work further discloses that the chemoselectivity of cross-coupling over homocoupling mainly relies on a suitable combination of two directing groups (i.e., a pair of strongly and weakly coordinating directing groups) rather than the electronically distinct properties between two substrates, which provides an inspiration for designing the matching directing group pair for the dual chelation-assisted oxidative Ar-H/Ar-H cross-couplings. Thus, this strategy allows the highly chemoselective cross-coupling between electronically similar coupling partners, which represents a challenging task in the oxidative Ar-H/Ar-H cross-coupling reactions.

Oxidation of benzyl alcohol is one of the industrial reactions utilized to produce chlorine-free benzaldehyde. Interestingly, supported gold nanoparticle catalysts are efficient towards the oxidation reaction of alcohol without involving any solvents, hence following the terms of green technology. In this study, nanoparticles of bimetallic gold palladium supported on TiO2 were synthesized using the sol-immobilization method. The catalysts were structurally characterized using X-ray Diffraction (XRD), Transition Electron Microscopy (TEM), and Brunauer Emmett Teller (BET) instruments to get insight into the synergistic effect between both Au and Pd. The catalytic activities of the prepared catalysts were evaluated towards the oxidation of benzyl alcohol over tertbutyl hydroperoxide (TBHP). The results obtained from the catalytic evaluation of the prepared catalysts indicated that 0.5 wt% Au-0.5 wt% Pd/TiO2 is the best catalyst among other ratios with a 3.1 +/- 0.8 nm particle size and the TEM results reveal the consistency value of a particle for each Au Pd ratio. The prepared catalyst consists of 0.50 wt% Au and 0.50 wt% Pd/TiO2 which exhibited remarkably enhanced catalytic activity (>19%) and selectivity of benzaldehyde (80%) when compared to another metal loading of the Au Pd catalyst. The reusability of the prepared catalyst was evaluated more than five times, and the results indicated minimal loss in activity where a low concentration of gold was leached (0.05 mg/L) under optimal reaction conditions.

Polysulfide anions are endowed with unique redox properties, attracting considerable attentions for their applications in alkali metals-sulfur batteries. However, the employment of these anionic species in redox catalysis for small molecule synthesis remains underdeveloped due to their moderate-poor electrochemical potential in the ground state, whereas some of them are characterized by photoabsorptions in visible spectral regions. Herein, we disclose the use of polysulfide anions as visible light photoredox catalysts for aryl cross-coupling reactions. The reaction design enables single-electron reduction of aryl halides upon the photoexcitation of tetrasulfide dianions (S-4(2-)). The resulting aryl radicals are engaged in (hetero)-biaryl cross-coupling, borylation, and hydrogenation in a redox catalytic regime involving S-4(center dot-) and S-4(2-)/S-3(center dot-)/S-3(2-) redox couples.

A series of novel isoxazolidines based on benzaldehyde derivatives have been synthesized from the cycloaddition of chiral menthone-based nitrone and allyl phenyl ethers. All synthetic compounds were assessed for their in vitro PPA, HPA and HLAG inhibitory activity. The results revealed that all targets exhibited better inhibitory effect against PPA (12.3 +/- 0.4 < IC50 < 38.2 +/- 0.9 mu M), HPA (10.1 +/- 0.4 < IC50 < 26.8 +/- 0.2 mu M) and HLAG (65.4 +/- 1.2 < IC50 < 274.8 +/- 1.1 mu M) when compared with the reference inhibitor, acarbose (IC50 = 284.6 +/- 0.3 mu M for PPA, 296.6 +/- 0.8 mu M for HPA, 780.4 +/- 0.3 mu M for HLAG) with the highest PPA inhibitory activity was ascribed to compound 3g against both PPA and HPA, and 3b against HLAG enzymes, respectively. Structural activity relationships (SARs) were also established for all synthesized compounds and the interaction modes of the most potent inhibitors (3g for PPA and HPA, 3b for HLAG) and the active site with residues of three enzymes were confirmed through molecular docking studies. Furthermore, a combination of molecular docking analysis with the in vitro activities can help to improve prediction success and encourages the uses of some of these molecules as potential alternatives toward the modulation of T2D.
