Ligand structure-driven self-assembly of Zn(NCS)(2) with a carbohydrazone ligand: A possible intermediate towards a [2 x2] metallic grid

In this work we have synthesized and characterized a new trinuclear heteroleptic discrete zin.(II) complex [Zn-3(HL)(2) (NCS)(4)], fabricated from a mixture of Zn(NO3)(2) and NaNCS with a symmetric and bulky carbohydrazone derived from carbohydrazide and benzoyl pyridine (H2L). The global structure and shape of complex are dictated by two monodeprotonated ligands HL – each coordinating the same Zn(II) ion through one of the pendant arms in an orthogonal fashion, yielding a distorted octahedral N4O2 coordination environment. The second coordination pocket of both ligands each traps Zn(NCS)(2) species, yielding an N4O coordination environment. The hexa- and pentacoordinated metals are separated by about 4 angstrom and positioned almost at a right angle (similar to 87 degrees) addressed by the orientation of organic ligands. The structure of [Zn-3 (HL)(2) (NCS)(4)] is mimicking grid-like structures and can be considered as a possible intermediate towards a [2 x2] metallic grid. The thiocyanate anions block two of three metal sites that could potentially serve as coordination nodes to fulfil the grid formation. A pair of molecules, arranged about an inversion center, are linked through a pair of (N)C-S center dot center dot center dot pi(Py) noncovalent interactions, which have been rationalized using density functional theory (DFT) calculations, and characterized using the noncovalent interaction plot (NCIplot) index and molecular electrostatic potential (MEP) surface computational tools.

Electrostatically Driven Guest Binding in Self-Assembled Molecular Network of Hexagonal Pyridine Macrocycle at the Liquid/Solid Interface: Symmetry Breaking Induced by Coadsorbed Solvent Molecules

We present here the construction of a self-assembled two-dimensional network at the liquid/solid interface using a hexagonal pyridine macrocycle which binds an organic cation in its intrinsic porous space by electrostatic interactions. For this purpose, a hexagonal pyridinylene-butadiynylene macrocycle (PyBM) having six octyloxymethyl groups, PyBM-C8, was synthesized. As guests, tropylium (Tr) tetrafluoroborate and trioxatriangulenium (TOTA) hexafluorophosphate were used. In this study, we focused on (i) the network patterns of PyBM-C8 which change in response to its concentration and (ii) the position of the guest immobilized in the porous space of the macrocycle. Scanning tunneling microscopy (STM) observations at the interface of 1,2,4-trichlorobenzene (TCB) and highly oriented pyrolytic graphite (HOPG) revealed that PyBM-C8 formed four different polymorphs, oblique, loose hexagonal, linear, and rectangular, depending on the solute concentration and annealing treatment. Solvent TCB molecules are likely coadsorbed to not only the intrinsically porous space of PyBM-C8 (internal TCB) but also the space outside of the macrocycle between its alkyl chains (external TCB) in most of the cases. Upon adding the guest cation, whereas small Tr was not visualized in the pore due to size mismatching, larger TOTA was clearly observed in each pore. In addition, based on high-resolution STM images of the rhombus packing pattern of PyBM-C8, we revealed experimentally that TOTA was placed at an off center position of the deformed hexagonal macrocyclic core in the rhombus pattern. On the basis of the molecular mechanics calculations, we hypothesize that the off-center location of TOTA is due to deformation of the hexagonal macrocycle through interaction with two external TCB molecules located at opposite edges of the macrocyclic core. Symmetry breaking of the macrocyclic host framework induced by coadsorbed surrounding solvent molecules thus plays a significant role in host-guest complexation at the liquid/solid interface.

Insights into the Phosphate Species on Niobia Treated with H3PO4

Solid acid catalysts are largely used in several industrial processes, and the development of materials with high activity, selectivity and reusability is a subject of study of research groups around the world. The improvement of oxide acidity could be performed by phosphation with phosphoric acid but the investigation of phosphated niobia is still incipient. In this work, niobia was treated with phosphoric acid solutions to generate catalysts with higher esterification activity at mild condition. The phosphated catalysts were obtained and characterized by XRD, N-2 adsorption, NH3 and pyridine chemisorption and FTIR, and were tested in the esterification of acetic acid with ethanol at 60 degrees C and RT. DFPT calculations indicated that H2PO4 group was the predominant phosphate species on the hydroxylated surface. Theoretical results also show that ethanol adsorbs preferentially at H2PO4 acidic sites on the phosphated catalyst as compared to acetic acid. [GRAPHICS] .

Synthesis of the 6-Substituted Imidazo[1,2-a]Pyridine-3-yl-2-Phosphonopropionic Acids as Potential Inhibitors of Rab Geranylgeranyl Transferase

Twelve phosphonopropionates derived from 2-hydroxy-3-imidazo[1,2-a]pyridin-3-yl-2-phosphonopropionic acid (3-IPEHPC) were synthesized and evaluated for their activity as inhibitors of protein geranylgeranylation. The nature of the substituent in the C6 position of imidazo[1,2-a]pyridine ring was responsible for the compound’s activity against Rab geranylgeranyl transferase (RGGT). The most active inhibitors disrupted Rab11A prenylation in the human cervical carcinoma HeLa cell line. The esterification of carboxylic acid in the phosphonopropionate moiety turned the inhibitor into an inactive analog.

An Efficient Sequential One-Pot Approach for the Synthesis of C3-Functionalized Imidazo[1,2-a]pyridines under Transition-Metal Free Conditions

A metal-free sequential one-pot three-component protocol is described for the synthesis of C3-functionalized imidazo[1,2-a]pyridines. A successive construction of imidazo[1,2-a]pyridine followed by iodine-catalysed sulfenylation has been achieved in a one-pot operation from readily available alpha-bromomethyl ketones, 2-aminopyridines and thiosulfonates. An immense array of 3-sulfenylimidazo[1,2-a]pyridines were obtained in good to high yields. Also, the method extended for the synthesis of C3-halogenated imidazo[1,2-a]pyridines using sodium halides in the presence of K2S2O8. Notably, the reaction between alpha-bromomethyl ketones and 2-aminopyridines in the presence of K2S2O8 to yield 3-bromo-2-aryl-imidazo[1,2-a]pyridines, thus implies alpha-bromomethyl ketones also served as brominating agent. Overall, the present sequential one-pot protocol is straightforward, operationally simple, tolerates a broad range of functional groups, and is reliable for gram-scale experiments.

Rotational spectrum and internal dynamics of the hydrogen-bonded pyrrole-pyridine aromatic pair

Non-covalent interactions determine the three-dimensional structure and activity of biological molecules. In this work, the pyrrole-pyridine complex considered as a model of the N-H center dot center dot center dot N hydrogen-bonded Watson-Crick base pairs has been generated in a supersonic expansion and characterized by chirped pulse Fourier transform microwave spectroscopy. The analysis of the unconventional spectral pattern of the 1:1 pyrrole-pyridine adduct and its C-13 and N-15 isotopologues reveal a non-planar complex, with a bent N-H center dot center dot center dot N hydrogen bond and large amplitude motion of the pyrrole subunit. The bent structure is likely to arise from the stablishment of the secondary C-H center dot center dot center dot N interaction between pyridine and pyrrole moieties. (C) 2020 Elsevier B.V.

Design, synthesis and biological evaluation of novel copper-chelating acetylcholinesterase inhibitors with pyridine and N-benzylpiperidine fragments

Cholinergic depletion is the direct cause of disability and dementia among AD patients. AChE is a classical and key target of cholinergic disorders. Some new inhibitors of AChE combining pyridine, acylhydrazone and N-benzylpiperidine fragments were developed in this work. The hit structure was optimized to yield the compound 21 with an IC50 value of 6.62 nM against AChE, while almost no inhibitory effect against BChE. ADMET predictions and PAMPA permeability evaluation showed good drug-like property. The higher activity with an intermediate alkyl chain substitution indicates a new binding mode of inhibitor with AChE. This finding provides new insights into the binding mechanism and is helpful for discovery of novel high-activity AChE inhibitors.

Design, Synthesis, Characterization and Application of BNPs@SiO2(CH2)(3)NH-CC-AMP-Pd (0) as a New Reusable Nano-Catalyst for Suzuki and Heck Cross-Coupling Reactions

A simple and effective method was used for the successful preparation of the Boehmite@(CH2)(3)NH-CC-AMP-Pd (0) NPs as an environmentally friendly heterogeneous nano-catalyst. The synthesized nano-catalyst was well identified by different techniques like FT-IR, XRD, XPS, TEM, SEM, EDX, TGA, mapping, and ICP analysis. The BNPs@SiO2(CH2)(3)NH-CC-AMP-Pd was used as a recoverable nano-catalyst for Suzuki-Miyaura and Mizoroki-Heck coupling reactions under mild, green and sustainable conditions with excellent yields (H2O, EtOH as solvent for Suzuki reaction and solvent-free conditions for Heck reaction). Also, the distribution of palladium on the catalyst surface is uniform and the average palladium size is between 20 and 30 nm. Compared to similar works, this protocol has some of the important aspects such as: thermal and mechanical stability of the catalyst, low palladium leaching (9.7%), the simplicity of the preparation, the availability of raw materials, not expensive, no need for neutral atmosphere, appropriate times, green conditions, use low amount of catalyst (1.42 mol%) and reused catalyst for several consecutive times (at least seven times).

Catalytic hydrogenation, hydrocracking and isomerization reactions of biomass tar model compound mixture over Ni-modified zeolite catalysts in packed bed reactor

Gas-phase conversion of a model mixture of biomass tar (5 wt% naphthalene and 95 wt% of 1-methylnaphthalene) into 2-methylnaphthalene liquid product and ethylene and propane gas mixture was carried out over different zeolites and metal promoted zeolites in a packed-bed reactor for the first time. In the present work, a series of MFI (H-ZSM-5), BEA (H-beta), FAU (H-Y, H-USY), and MOR (H-Mordenite) zeolites were investigated. The effect of Ni metal addition on the promotion of parent zeolite catalysts was studied. The most successful catalysts were characterized by BET, ICP-AES, XRD, HRSEM, STEM-HAADF, and STEM-BF with EDXS, NH3-TPD, H-2-TPR, TGA, and pyridine-DRIFT techniques. The superior performance in comparison to the other studied catalysts was established over the 5 wt%Ni/H-ZSM-5 (SiO2/Al2O3 = 30) with 96.2 mol% of selectivity to 2-methylnaphthalene in the liquid phase, 90 mol% total conversion with the highest part (82.9 wt%) of ethylene and propane in the gas phase after 24 h time-on-stream. This high catalytic performance of the 5 wt%Ni/H-ZSM-5 catalyst can be attributed to the presence of the high mesopore volume, pore diameter, and high mesopore surface area, the existence of the redox active sites, and the presence of strong Lewis acid sites due to synergetic interaction between Ni metal species and zeolite acid support. Based on the product distributions observed, the reaction scheme of the conversion of biomass tar model mixture of naphthalene and 1-methylnaphthalene over studied catalysts was proposed. Our catalytic results obtained over pristine and Ni-modified zeolite catalysts shed light on the potential use of these catalysts in the biomass tar valorization process under atmospheric pressure.

The Aza-hexadehydro-Diels-Alder Reaction

The generation of pyridynes from diyne nitriles is reported. These cyano-containing precursors are analogues of the triyne substrates typically used for the hexadehydro-Diels-Alder (HDDA) cycloisomerization reactions that produce ring-fused benzynes. Hence, the new processes described represent aza-HDDA reactions. Depending on the location of the nitrile, either 3,4-pyridynes (from 1,3-diynes containing a tethered cyano group) or 2,3-pyridynes (from 1-cyanoethyne derivatives containing a tethered alkyne) are produced. In situ trapping of these reactive intermediates leads to highly substituted and functionalized pyridine derivatives. In several instances, unprecedented pyridyne trapping reactions are seen. Differences in reaction energetics between the aza-HDDA substrates and that of their analogous HDDA (triyne) substrates are discussed.
