In each of the compounds 1-[(1,3-benzodioxol-5-yl)methyl]-4-(3-fluorobenzoyl)piperazine, C19H19 FN2O3 (I), 1-[(1,3-benzodioxol-5-yl)methyl]-4-(2,6-difluorobenzoyl)piperazine, C19H18F2N2O3 (II), and 1-[(1,3-benzodioxol-5-yl)methyl]-4-(2,4-dichlorobenzoyl)piperazine, C19H19Cl2N2O3 (III), the piperazine rings adopt a chair conformation with the (1,3-benzodioxol-5-yl)methyl substituent occupying an equatorial site: the five-membered rings are all slightly folded across the O center dot center dot center dot O line leading to envelope conformations. The dihedral angle between the planar amidic fragment and the haloaryl ring is 62.97 (5)degrees in (I) but 77.72 (12)degrees and 75.50 (5)degrees in (II) and (III), respectively. Despite their similarity in constitution and conformation, the supramolecular interactions in (I)-(III) differ: in (I), a combination of C-H center dot center dot center dot O and C-H center dot center dot center dot pi(arene) hydrogen bonds links the molecules into a three-dimensional framework structure, but there are no hydrogen bonds of any sort in either (II) or (III), although the structure of (III) contains a short Cl center dot center dot center dot Cl contact between inversion-related pairs of molecules.

Transition metal-catalyzed cross-couplings have been widely employed in the synthesis of many important molecules in synthetic chemistry for the construction of diverse C-C bonds. Conventional cross-coupling reactions require active electrophilic coupling partners, such as organohalides or sulfonates, which are not environmentally friendly enough. Herein, we disclose the first nickel-catalyzed Suzuki-Miyaura cross-coupling of aryl anhydrides and arylboronic acids for the synthesis of biaryls in a decarbonylation manner. The reaction tolerates a wide range of electron-withdrawing, electron-neutral, and electron-donating substituents in this process.

Heteroleptic triorganobismuth (V) complexes of general formula, R3Bi(OOCR’)(2) (1-7), where R = C6H5 (1-3), p-CH3C6H4 (4-7) and R’ = 3,5-Cl2C6H3 (1, 5); 3,4,5-(OCH3)(3)C6H2 (2, 6); 3-CH3C6H4 (3,7); 2-OH-3-OCH3C6H3 (4) have been synthesized and fully characterized by FT-IR, H-1 &C-13 NMR spectroscopy, single crystal X-ray crystallography and elemental analysis. The molecular geometry observed for the compounds is predominantly distorted trigonal bipyramidal, the fact which was subsequently authenticated through X-ray analyses for (1-4). All the synthesized compounds have been bio-assayed for antileishmanial (Leishmania tropica KWH23) and Jack beans urease inhibitory activity, and human Lymphocytes were used to measure the general toxicity. Of these, (4) proved to be highly effective against the target species (Leishmania tropica KWH23), while being non-toxic towards the mammalian cells at levels below 0.74 mu gmL(-1), making it highly promising drug candidate. The high activities for (2, 4, and 6) against Jack beans Urease as compared to the reference standard demonstrate their significance in searching of therapeutic agents in future programs. The significant binding score of (2&4) against H. pylori in molecular docking studies further revealed their importance in future drug discovery processes.

Because of their stable orientations and their minimal interference with native DNA interactions and folding, emissive isomorphic nucleoside analogues are versatile tools for the accurate analysis of DNA structural heterogeneity. Here, we report on a bifunctional trifluoromethylphenylpyrrolocytidine derivative ((FP)dC) that displays an unprecedented quantum yield and highly sensitive F-19 NMR signal. This is the first report of a cytosine-based dual-purpose probe for both fluorescence and F-19 NMR spectroscopic DNA analysis. (FP)dC and (FP)dC-containing DNA were synthesized and characterized; our robust dual probe was successfully used to investigate the noncanonical DNA structure, i-motifs, through changes in fluorescence intensity and F-19 chemical shift in response to i-motif formation. The utility of (FP)dC was exemplified through reversible fluorescence switching of an (FP)dC-containing i-motif oligonucleotide in the presence of Ag(i) and cysteine.

Safety of 1,3-Dimethoxybenzene. Recently I am researching about FUNCTIONALIZATION; ARYLSILANES; OXIDATION; ARENES; LIGAND, Saw an article supported by the NIHUnited States Department of Health & Human ServicesNational Institutes of Health (NIH) – USA [R35 GM130387, S10OD024998, NIH S10OD023532].

Phenanthroline ligands and [Ir(cod)(OMe)](2) form complexes that catalyze the silylation of aromatic and aliphatic C-H bonds. However, no experimental data on the identity of complexes related to the mechanism of this process or the mechanisms by which they react to functionalize C-H bonds have been reported. Herein, we describe our studies on the mechanism of the iridium-catalyzed silylation of aryl C-H bonds. The resting state of the catalyst is an iridium disilyl hydride complex (phenanthroline)Ir(SiMe(OTMS)(2))(2)(H)(L), in which L varies with the arene and additives. An iridium disilyl hydride complex was isolated, characterized, and allowed to react with arenes to form aryl silanes. The kinetics of the reactions of electron-rich and electron-poor arenes showed that the rate-limiting step varies with the electronic properties of the arene. Computational studies on related iridium silyl complexes revealed that the high activity of iridium complexes containing sterically encumbered phenanthroline ligands is due to a change in the number of silyl groups bound to iridium between the resting state of the catalyst containing the hindered phenanthroline and that containing less-hindered phenanthroline.

The organocatalytic enantio- and diastereoselective cycloetherification of 1,3-cyclohexanedione-bearing enones involving the in situ generation of chiral cyanohydrins was developed. This transformation offers the first catalytic asymmetric approach to oxadecalin derivatives containing contiguous tetrasubstituted chiral carbons at the bridge heads of the fused ring systems. Depending on substituents, both cis- and trans-decalin-type scaffolds were synthesized with good to excellent stereoselectivities, and a range of functional groups accumulated on the chiral quaternary carbon moieties of the trans-oxadecalin derivatives.

The extensively developed ene-type enantioselective cycloisomerization of classical 1,n-enynes provides an efficient approach to chiral cyclic 1,4-dienes. In contrast, the catalytic asymmetric heteroarenyne (heteroarene-alkyne) cycloisomerization involving the dearomative transformation of endocyclic aromatic C=C bonds remains unknown. Herein, we communicate a PdH-catalyzed enantioselective heteroarenyne cycloisomerization reaction of alkyne-tethered indole substrates (formal 1,5- and 1,6-enynes). Based on this strategy, a variety of structurally diverse chiral spiro and fused indoline derivatives bearing quaternary stereocenters and exocyclic C=C bonds are afforded in moderate to excellent yields and excellent enantioselectivities (up to 98 % ee). The classical ene-type enantioselective 1,5-enyne cycloisomerization of N-vinylpropiolamides is also developed to afford chiral 2-pyrrolones in good to excellent ee values.

Recommanded Product: 151-10-0. I found the field of Materials Science; Physics very interesting. Saw the article Flexible-color tuning and white-light emission in three-, four-, and five-component host/guest co-crystals by charge-transfer emissions as well as effective energy transfers published in 2019, Reprint Addresses Ono, T; Hisaeda, Y (corresponding author), Kyushu Univ, CMS, Grad Sch Engn, Dept Chem & Biochem, Fukuoka, Fukuoka 8190395, Japan.; Ono, T (corresponding author), Japan Sci & Technol Agcy JST, PRESTO, 4-1-8 Honcho, Kawaguchi, Saitama 3320012, Japan..

Three-, four-, and five-component host/guest crystals with multi-color and white light emission is described. Our strategy is based on the confinement of aromatic donor guests in supramolecular acceptor hosts. The supramolecular acceptor hosts (NDI-TPFB) were composed of N,N’-dipyrid-3-yl-1,4,5,8- naphthalenediimide (NDI) with two tris(pentafluorophenyl) borane (TPFB) linked by boron-nitrogen dative bonds as Lewis acid-base pairs, which spontaneously formed upon mixing the components. In the first part, a set of three-component crystals with 14 different aromatic guests were characterized to elucidate the structure-property relationships. In the latter part, a series of 17 types of four-and fivecomponent crystals were formed with the use of binary or ternary guest inclusion systems, and their structural and photophysical properties were investigated. Among them, 14 types of crystals were formed effectively without destroying the crystal structure, as determined by X-ray diffraction and fluorescence microscopy. Notably, flexible color tuning, including white light emission, was realized by tuning the guest ratio and the combinations. Various intermolecular interactions such as C-H center dot center dot center dot F interactions, pi-pi stacking, charge-transfer interactions, and inclusion phenomena were important for forming the crystals. This approach that yields a rational solution of multicomponent crystals could be potentially useful for obtaining novel photofunctional solid-state systems.

Sustainable technologies rely on the development of universal catalyst materials. While a lot of the attention has been given to improving the performance of one single catalyst material for one specific application, there is still a need to find ways to develop catalysts that can simultaneously be utilized for several chemo- and electrocatalytic processes. In this work, we have surveyed a series of novel, cobalt-based catalyst materials derived from an amorphous MOF in an array of diverged applications. Specifically, we have focused on organic transformations such as oxidative of alkylarenes and benzylic homocoupling reactions as well as several electrocatalytic processes, which directly relate to energy conversion and storage devices, such as oxygen reduction (ORR), oxygen evolution (OER) and hydrogen evolution (HER) reactions. We have observed that only one material, TAL-2-900, delivered the optimal solution. The stability and recyclability of this unique multifunctional material has been examined.
