Toluene Dioxygenase-Catalyzed cis-Dihydroxylation of Quinolines: A Molecular Docking Study and Chemoenzymatic Synthesis of Quinoline Arene Oxides

Molecular docking studies of quinoline and 2-chloroquinoline substrates at the active site of toluene dioxygenase (TDO), were conducted using Autodock Vina, to identify novel edge-to-face interactions and to rationalize the observed stereoselective cis-dihydroxylation of carbocyclic rings and formation of isolable cis-dihydrodiol metabolites. These in silico docking results of quinoline and pyridine substrates, with TDO, also provided support for the postulated cis-dihydroxylation of electron-deficient pyridyl rings, to give transient cis-dihydrodiol intermediates and the derived hydroxyquinolines. 2-Chloroquinoline cis-dihydrodiol metabolites were used as precursors in the chemoenzymatic synthesis of enantiopure arene oxide and arene dioxide derivatives of quinoline, in the context of its possible mammalian metabolism and carcinogenicity.

Redox-controlled syndio-specific polymerization of styrene catalyzed by ferrocenyl functionalized half-sandwich scandium complexes

Redox-controlled polymerization is one of the new and efficient strategies to precisely construct the microstructures of polymeric materials, and thus has received increasing attention in the chemical community. Salt metathesis of ScCl3 with 1 equiv. of Fc(1-C9H6)Li (where Fc = ferrocenyl group), followed by the addition of 2 equiv. of LiCH2C6H4NMe2-o in THF at room temperature gave the ferrocenyl functionalized half-sandwich scandium bis(o-dimethylaminobenzyl) complex [Fc(1-C9H6)]Sc(CH2C6H4NMe2-o)(2) (1) in 89% isolated yield. This complex was characterized by elemental analysis, FT-IR spectroscopy, NMR spectroscopy and single-crystal X-ray diffraction. Treatment of 1 with 1 equiv. of [Ph3C][B(C6F5)(4)] in THF generated the THF-coordinated cationic half-sandwich scandium mono(o-dimethylaminobenzyl) complex {[Fc(1-C9H6)]Sc(CH2C6H4NMe2-o)}{[B(C6F5)(4)]} (2-THF2). Switching in situ between the oxidized and reduced forms of active THF-free species (originally generated from 1/[Ph3C][B(C6F5)(4)] in situ) resulted in the redox-controlled syndio-specific polymerization of styrene.

Synthesis of a coronene analogue containing an amide bond by Pd-mediated intramolecular C-C bond formation of 2-halogenated 4-(alkylamino)benzoic acid cyclic trimer

A coronene analogue containing amide linkage was synthesized from a halogenated cyclic triamide by palladium-mediated intramolecular C-C bond formation. The cyclic triamide was formed from the condensation of 2-chloro-4-(isobutylamino)benzoic acid in the presence of dichlorotriphenylphosphorane in 1,1,2,2-tetrachloroethane. By contrast, the condensation of 2-bromo counterpart required silicon tetrachloride in pyridine. The intramolecular C-C bond formation, which yielded the target coronene analogue, occurred during the reaction of bromo-substituted cyclic triamide with palladium(II) acetate, triphenylphosphine, and potassium carbonate in N,N-dimethylformamide.

Co-pyrolysis of textile dyeing sludge and red wood waste in a continuously operated auger reactor under microwave irradiation

The eco-friendly disposal of textile dyeing sludge (TDS) has become a worldwide environmental issue due to their complexity and toxicity. In this study, co-pyrolysis of TDS and red wood waste (RWW) in a continuously operated auger reactor under microwave irradiation was investigated, which was more environmentally friendly and created higher value added products. Effects of pyrolysis temperature and RWW ratio were studied to evaluate product distribution and properties. Increase of temperature and RWW ratio resulted in decrease in char yield and increase in gas yield. The contents of CO, CH4, and H-2 increased significantly with RWW ratio increased at 650 degrees C. The content of pyridines, amines, and nitriles enhanced sharply with increasing temperature from 450 to 750 degrees C. Co-pyrolysis promoted the Maillard reaction and cracking of nitrogen-containing pigments, forming large quantities of N-heterocyclics in bio-oil. Sludge char obtained by pyrolysis of TDS at 650 degrees C had a greater sulfur retention ability than chars from co-pyrolysis. The highest methylene blue number (372.25 mg/g) and iodine adsorption value (332.42 mg/g) were achieved from TDS and biochar (750 degrees C, 30 wt% RWW ratio), respectively. Fe(III) in Fe2O3 was reduced to Fe(II) in Fe3O4 and further partially reduced to metallic Fe in biochar. (C) 2020 Elsevier Ltd. All rights reserved.

How to select ionic liquids as extracting agents systematically: a special case study for extractive denitrification processes

Extractive denitrification (EDN) of shale oil using ionic liquids (ILs) as the extracting agent has good industrial prospects. In such processes, ILs with higher selectivity to N-compounds and lower solubility in shale oil are desired to improve the EDN efficiency, and reduce the loss of ILs and the contamination of shale oil. In the present study, we employed COSMO-RS to calculate the selectivity of 70 ILs to the typical N-compounds (pyridine, quinoline and indole). The influence of the IL structural characteristics, composition of shale oil and properties of N-compounds are investigated from a micro-level view with the sigma-surface and sigma-profile. The selectivity strongly depends on anionic species and it is greatly influenced by hydrogen bonding (HB) and pi-pi interaction between N-compounds and ILs. ILs composed of [H2PO4](-) and [MeSO3](-) with larger HB donor energy show higher selectivity to the basic N-compounds, while ILs composed of [Ac](-) with larger pi-electron cloud density show higher selectivity to the non-basic N-compounds. Anions with stronger polarity have lower solubility in shale oil. Moreover, experimental determinations of EDN indicated that [C(4)py][H2PO4]/[C(4)mim][H2PO4] and [C(2)mim][Ac]/[C(2)py][Ac] have good EDN performance for quinoline/pyridine with efficiency of 100% and for indole with efficiency of 91%, respectively. This work presents a theoretical basis to design and select ILs having higher selectivity for N-compounds and lower solubility in shale oil for use in denitrification.

Quantitative characterisation of the ring normal modes. Pyridine as a study case

In the present work, the vibrational normal modes (NM) of pyridine were revisited. Quantum Chemical calculations were performed to help understand the true nature of some ring related vibrational normal modes (RNM) and how they may be correlated with the electronic structure on the ring. The 27 vibrational normal modes were decomposed into the molecular internal coordinates, and the interest was focused on 7 of them, involving the in plane ring motion. The electronic structure was analysed through frontier Molecular Orbitals (MO), maps of Molecular Electrostatic Potential surfaces (MEPs) and Natural Bond Orbital (NBO) analysis in a dynamic manner, wherein, each vibration was scanned. The present investigation is aimed to provide the Reader with a quantitative characterisation of the RNMs of pyridine. (C) 2020 Elsevier B.V. All rights reserved.

Dimetallic Palladium-NHC Complexes: Synthesis, Characterization, and Catalytic Application for Direct C-H Arylation Reaction of Heteroaromatics with Aryl Chlorides

A series of dimetallic palladium(II)-NHC complexes comprised of 1,4-naphthalenyl or 9,10-anthracenyl spacer sandwiched between two imidazole rings was successfully synthesized. These complexes were characterized by H-1 and C-13{H-1} NMR spectroscopy and elemental analysis. The structures of two dimetallic palladium complexes and a related mononuclear palladium complex to be used for comparative studies were further characterized by X-ray diffraction. The dimetallic palladium complex with the 9,10-anthracenyl linker was very efficient in catalyzing direct C-H arylation reactions of heteroaromatic compounds (imidazoles, imidazo[1,2-a]pyridine, and thioazole) with a broad range of aryl chlorides, employing a mild monopalladium loading of 1.5 mol%. It allows for the effective use of aryl chlorides to prepare arylated heterocycles, previously only accessible with the more reactive bromide counterparts. Importantly, the catalytic activity of the dimetallic precatalyst was found to be higher than that of an analogous mononuclear complex.

Unprecedented Formation of 2-Chloro-5-(2-chlorobenzyl)-4,5,6,7-tetrahydrothieno[3,2-c]pyridine 5-oxide via Oxidation-Chlorination Reaction Using Oxone: A Combination of Synthesis and 1D-2DNMR Studies

Ticlopidine hydrochloride (1 center dot HCl, Ticlid (TM)) is a prodrug that, through bioactivation by cytochrome P450 (CYP), interacts with the P2Y(12) receptor ADP inhibiting platelet aggregation. This prodrug mediated by a multistep biochemical process led to the formation of active metabolic intermediates. In this work, an eco-friendly and efficient protocol for the formation of 2-chloroticlopidine (2) using 1 center dot HCl and oxone in aqueous methanol media via an unprecedented formation of reactive thienopyridine intermediate 2-chloro-5-(2-chlorobenzyl)-4,5,6,7-tetrahydrothieno[3,2-c]pyridine 5-oxide (4) was developed. The key to success of 4 is the oxidation of tertiary amines to N-oxides, followed by mono-chlorination at the 2-position of the thiophene ring by oxidation of the chloride counterion of this prodrug. In addition, we use the 1D and 2DNMR techniques as a tool to monitor reaction progress, and for assigning the signals of all compounds involved, especially for the novel thienopyridine 4.

Rare-Earth-Metal-Catalyzed Synthesis of Azaindolines and Naphthyridines via C-H Cyclization of Functionalized Pyridines

We report herein a rare-earth-metal-catalyzed insertion of a 2-pyridine C(sp(2))-H bond into an intramolecular unactivated vinyl bond. This reaction provides streamlined access to a range of azaindolines in moderate to excellent yields. The salient features of this reaction include simple and mild reaction conditions, 100% atom efficiency, and wide substrate scope. This methodology is also used to construct other nitrogen-containing compounds such as naphthyridine derivatives. A plausible mechanism for the formation of azaindolines involving initial C-H bond activation by the lanthanide complex followed by C=C insertion into a Ln-C bond to form an alkyl lanthanide species that subsequently undergoes cyclization is proposed.
