A new series of 4-(3-nitrophenyl)thiazol-2-ylhydrazone derivatives were designed, synthesised, and evaluated to assess their inhibitory effect on the human monoamine oxidase (hMAO) A and B isoforms. Different (un)substituted (hetero)aromatic substituents were linked to N1 of the hydrazone in order to establish robust structure-activity relationships. The results of the biological testing demonstrated that the presence of the hydrazothiazole nucleus bearing at C4 a phenyl ring functionalised at the meta position with a nitro group represents an important pharmacophoric feature to obtain selective and reversible human MAO-B inhibition for the treatment of neurodegenerative disorders. In addition, the most potent and selective MAO-B inhibitors were evaluated in silico as potential cholinesterase (AChE/BuChE) inhibitors and in vitro for antioxidant activities. The results obtained from molecular modelling studies provided insight into the multiple interactions and structural requirements for the reported MAO inhibitory properties.

An oxa-[2,3] sigmatropic rearrangement involving arynes is reported featuring the umpolung of ketones, where the C = O bond polarity is reversed. The in situ-generated sulfur ylides from beta-keto thioethers and arynes undergo efficient rearrangement allowing the facile and robust synthesis of functionalized enol ethers in high yields and excellent functional group compatibility. Preliminary mechanistic studies rule out the possibility of Pummerer-type rearrangement operating in this case.

Methanol is a potential hydrogen source and C-1 synthon, which finds interesting applications in both chemical synthesis and energy technologies. The effective utilization of this simple alcohol in organic synthesis is of central importance and attracts scientific interest. Herein, we report a clean and cost-competitive method with the use of methanol as both C-1 synthon and H-2 source for selective N-methylation of amines by employing relatively cheap RuCl3.xH(2)O as a ligand-free catalyst. This readily available catalyst tolerates various amines comprising electron-deficient and electron-donating groups and allows them to transform into corresponding N-methylated products in moderate to excellent yields. In addition, few marketed pharmaceutical agents (e. g., venlafaxine and imipramine) were also successfully synthesized via late-stage functionalization from readily available feedstock chemicals, highlighting synthetic value of this advanced N-methylation reaction. Using this platform, we also attempted tandem reactions with selected nitroarenes to convert them into corresponding N-methylated amines using MeOH under H-2-free conditions including transfer hydrogenation of nitroarenes-to-anilines and prepared drug molecules (e. g., benzocaine and butamben) as well as key pharmaceutical intermediates. We further enable one-shot selective and green syntheses of 1-methylbenzimidazole using ortho-phenylenediamine (OPDA) and methanol as coupling partners.

Structural and third-order nonlinear optical (NLO) properties of two D-pi-A-pi-A [(2E)-3-(3-chlorophenyl)-1-(3-nitrophenyl)prop-2-en-1-one (3C3NC) and (2E)-3-(4-fluorophenyl)-1-(4-nitrophe nyl)prop-2-en-1-one (FNC)] and one D-pi-A-pi-D [(2E)-1-(9-anthryl)-3-(4-fluorophenyl) prop-2-en-1-one (FANC)] type chalcone derivatives were investigated experimentally as well as theoretically. All the three chalcones are centrosymmetric (CS) and crystallized in P2(1)/c space group. In crystal packing, all compounds exhibit CeH center dot center dot center dot O hydrogen bonds and pi center dot center dot center dot pi interactions. From UV-Vis-NIR absorption spectra, the cut-off wavelength and optical band gaps of the chalcones were evaluated. The thermal stability and the melting point of the chalcones were determined from the TGA/DTA techniques. The ultrafast third-order NLO properties of the three chalcones in solution (0.01 M) were evaluated by Z-scan technique using femtosecond (fs) pulses from Ti: Sapphire laser (similar to 150 fs, 80 MHz, 800 nm). Third-order nonlinear absorption (NLA) coefficient (beta similar to 10(-9) cmW(-1)), nonlinear refraction (NLR) index (n(2)similar to 10(-14) cm(2)W(-1)), susceptibility (chi((3)) similar to 10(-12) esu) and molecular hyperpolarizability (gamma(h) similar to 10(-31) esu) were unambiguously determined. The chalcones satisfy the condition to observe reverse saturable absorption (RSA) mechanism (sigma(ex) > sigma(g)). Further, the larger values of sigma(ex)/sigma(g) (similar to 2-3) indicate that the chalcones would exhibit remarkable optical limiting property. The estimated optical limiting (OL) threshold values are in the order of mu J/cm(2). Further, all the chalcones have satisfied the one-photon and two-photon figures of merit conditions (W > 1 and T < 1) for the optical switching applications. In addition to experimental findings, the optimized geometry, HOMO-LUMO energy gap, NLO parameters such as electronic dipole moment, polarizability, first and second hyperpolarizabilities of all the three chalcones were determined theoretically (DFT) for different wavelength at B3LYP/6-311 thorn G (d,p) basic set. The experimentally determined second-order susceptibilities (Z-scan technique) are reasonably in agreement with the computational values (TD-DFT). The MEP surface revealed that the 3C3NC, FNC and FANC molecules have some potential sites for electrophilic and nucleophilic attack. The experimental and computational NLO data clearly suggest that the nonlinearity of chalcone molecules greatly depends on the electron donor and acceptor strengths of the substituents. Further, all the chalcones are potential materials for optical limiting and optical switching applications. (C) 2020 Elsevier B.V. All rights reserved. COA of Formula: C8H7NO3.

Site-specific functionalization of sp3 C-H bonds adjacent to a nitrogen atom is one of the unexplored heterogeneous transformations. Aiming at alpha-arylation of glycine derivative for rapid access to indolylglycines without the aid of bases, a chemically robust and two-dimensional COF is prepared. Integration of [2,2 ‘]bipyridyl (Bpy) unit benefits active homogeneous complex Ru(Bpy)22+ to anchor over the framework backbone to devise Ru-COF that acts as unprecedented visible light photocatalyst towards cross-dehydrogenative coupling of secondary amines with indoles in excellent yield at room temperature, under aerobic condition. Ru-COF shows admirable reusability and superior activity to that of Ru(Bpy)3Cl2, while substrate variation studies delineate wide ranges of functional group tolerance. To the best of Ru-COF, atom-economic C-H functionalization is realized as iminium ion is in situ generated. The photocatalytic route is detailed from astute modulation of optical band-gap in light of density-functional theory studies and experimental results, which validates single-electron-transfer pathway.

I found the field of Chemistry very interesting. Saw the article Mn(III) active site in hydrotalcite efficiently catalyzes the oxidation of alkylarenes with molecular oxygen published in 2021. Formula: C8H7NO3, Reprint Addresses Zhou, WY; He, MY (corresponding author), Changzhou Univ, Jiangsu Key Lab Adv Catalyt Mat & Technol, Changzhou 213164, Peoples R China.. The CAS is 100-19-6.

Developing efficient heterogeneous catalytic systems based on easily available materials and molecular oxygen for the selective oxidation of alkylarenes is highly desirable. In the present research, NiMn hydrotalcite (Ni2Mn-LDH) has been found as an efficient catalyst in the oxidation of alkylarenes using molecular oxygen as the sole oxidant without any additive. Impressive catalytic performance, excellent stability and recyclability, broad applicable scope and practical potential for the catalytic system have been observed. Mn3+ species was proposed to be the efficient active site, and Ni2+ played an important role in stabilizing the Mn3+ species in the hydrotalcite structure. The kinetic study showed that the aerobic oxidation of diphenylmethane is a first-order reaction over Ni2Mn-LDH with the activation energy (E-a) and pre-exponential factor (A(0)) being 85.7 kJ mol(-1) and 1.8 x 109 min(-1), respectively. The Gibbs free energy (Delta G(not equal)) was determined to be -10.4 kJ mol(-1) K-1 for the oxidation based on Eyring-Polanyi equation, indicating the reaction is exergonic. The mechanism study indicated that the reaction proceeded through both radical and carbocation intermediates. The two species were then trapped by molecular oxygen and H2O or hydroxyl species, respectively, to yield the corresponding products. The present research might provide information for constructing highly efficient and stable active site for the catalytic aerobic oxidation based on available and economic material.
