Solvent-free, atom-efficient, and mechanochemically activated reactions have emerged as synthetic strategy for sustainable chemistry. Herein we report a new mechanochemical approach for the amide coupling of carboxylic acids and amines, mediated by combination of (1-cyano-2-ethoxy-2-oxoethylidenaminooxy)-dimethylaminomorpholinocarbenium hexafluorophosphate (COMU) or N,N,N’,N’-tetramethylchloroformamidinium hexa-fluorophosphate (TCFH) and K2HPO4. The method delivers a range of amides in high yields (70-96%) and fast reaction rates. The reaction protocol is mild, keeps stereochemical integrity of the adjacent to carbonyl stereocenters, and streamlines isolation procedure for solid amide products. Minimal waste is generated due to the absence of bulk solvent. We show that K2HPO4 plays a dual role, acting as a base and a precursor of reactive acyl phosphate species. Amide bonds from hindered carboxylic acids and low-nucleophilic amines can be assembled within 90 minutes by using TCFH in combination with K2HPO4 or N-methylimidazole. The developed mechanochemical liquid-assisted amidation protocols were successfully applied to the challenging couplings of all six carboxylate functions of biotin[6]uril macrocycle with phenylalanine methyl ester, resulting in 80% yield of highly pure hexa-amide-biotin[6]uril. In addition, fast and high-yielding synthesis of peptides and versatile amide compounds can be performed in a safe and environmentally benign manner, as verified by green metrics.

Published in ROYAL SOC CHEMISTRY in CAMBRIDGE ,Authors: Ganji, N; Karimi, B; Najafvand-Derikvandi, S; Vali, H. The CAS is 99-04-7. Through research, I have a further understanding and discovery of 3-Methylbenzoic acid. Name: 3-Methylbenzoic acid

Preparation of an ordered mesoporous polypyrrole/carbon (PPy/OMC) composite has been described through a two-step nanocasting process using KIT-6 as a template. Characterization of the PPy/OMC nanocomposite by various analysis methods such as TEM, XRD, TGA, SEM and N-2 sorption confirmed the preparation of a material with ordered mesoporous structure, uniform pore size distribution, high surface area and high stability. This nanocomposite was then used for the immobilization of palladium nanoparticles. The nanoparticles were almost uniformly distributed on the support with a narrow particle size of 20-25 nm, confirmed by various analysis methods. Performance of the Pd@PPy/OMC catalyst was evaluated in the aerobic oxidation of various primary and secondary alcohols on water as a green solvent, giving the corresponding carboxylic acids and ketones in high yields and excellent selectivity. The catalyst could also be reused for at least 10 reaction runs without losing its catalytic activity and selectivity. High catalytic efficiency of the catalyst can be attributed to a strong synergism between the PPy/OMC and that of supported Pd nanoparticles.

An eco-friendly and a simple ipso-nitration protocol for a series of aliphatic and (hetero)aromatic carboxylic acids using nitronium tetrafluoroborate, 1-hexyl-3,4,5-trimethyl-1H-imidazolium tetrafluoroborate and base is reported. While contrasted with recently known decarboxylative ipso-nitration strategies for the preparation of nitro compounds, this protocol does not require a toxic metal catalyst and harmful volatile organic solvents. Moreover, this method is perfect for a broad range of functional groups and affords exclusively the ipso-nitrated product in moderate to good yields. (C) 2019 Elsevier Ltd. All rights reserved.

A photocatalyst-free and mild visible light photochemical procedure for C(sp(3))-H arylation of amides is described. The reaction proceeds via an electron donor-acceptor (EDA) complex between an electron-rich arene substrate and electron-poor persulfate oxidant. C(sp(3))-H arylation of the amide occurs selectively with the most electron-rich arene of the substrate. Mechanistic studies corroborate the reaction taking place in a solvent cage holding components in a close proximity.

Herein, we present a nickel-catalyzed three-component reductive alkylacylation of electron-deficient activated alkenes with tertiary alkyl bromides and acid anhydrides. This method enables the efficient preparation of a variety of ketones with broad substrate scope and high functionality tolerance starting from simple precursors. On the basis of the preliminary mechanistic investigations, a catalytic cycle involving the synergistic interaction of nickel, zinc, and MgCl2 is proposed as the major reaction pathway.

Metal-free Friedel-Crafts benzylation (FCB) of scarcely reactive arenes and heteroarenes was performed under on-water conditions by an environmentally sustainable procedure. The catalytic strategy exploits the hydrophobicity of the resorcinarene macrocycle 1 a. The proposed mechanism is based on the activation of benzyl chloride by H-bonding interactions with catalyst 1 a. In fact, under on-water conditions the hydrophobic amplification of the strength of the H-bonding interactions between the OH groups of the resorcinarene catalyst and the chlorine atom of benzyl chloride leads to polarization of the C-Cl bond, which consequently promotes electrophilic attack of the pi nucleophile. Thus, many arenes and heteroarenes were efficiently benzylated under mild on-water conditions by using resorcinarene 1 a as catalyst. The FCB of benzene is industrially relevant for the synthesis of diphenylmethane, and hence the on-water procedure was extended to the gram-scale synthesis of diphenylmethane, starting from benzene and benzyl chloride in the presence of resorcinarene catalyst 1 a.

Alkoxyamide has been reported as a catalyst for the activation ofN-bromosuccinimide to perform bromocyclization and bromination of a wide range of substrates in a lipophilic solvent, where adequate suppression of the background reactions was observed. The key feature of the active site is the alkoxy group attached to the sulfonamide moiety, which facilitates the acceptance as well as the delivery of bromonium species from the bromine source to the substrates.

A novel series of 4-substituted-3,4-dihydrobenzo[h]quinoline-2,5,6(1H)-triones as NQO1-directed anti-tumor agents were designed, synthesized, biologically evaluated. Compounds 3n, 3o and 3j proved to be good NQO1 substrates that showed increased metabolic rates relative to that of beta-lapachone. In addition, 3n, 3o and 3j potently inhibited the growth of NQO1-rich breast cancer MCF-7 cell, liver hepatocellular HepG2 cell, and lung cancer A549 cell. In cellular mechanistic studies, the representative compound 3o triggered ROS generation depending on the NQO1 dose, and induce HepG2 cell apoptosis by the generated oxidative stress. In HepG2 xenografts mouse model, at the dose of 20 mg/kg, 3o remarkably suppressed the tumor growth without affecting the animal weights. (C) 2020 Elsevier Masson SAS. All rights reserved.

The nitrogen and phosphorus co-doped graphene-like carbon (NPG) is cost-effective fabricated by simple ball-milling and thermal treatment. The as-prepared NPG can be used as a metal-free catalyst for selective catalytic oxidation of aromatic alcohols to their corresponding acids by using TBHP and O-2 as the oxidant in water. It is observed that various aromatic alcohols bearing electron-donating/withdrawing groups can be oxidized to the corresponding acids in excellent yields. No dehalogenation and steric-hindrance effects are detected in this oxidation process. In addition, the NPG catalyst can be easily separated and efficiently reused seven times, showing good recyclability.

This article presents a detailed comprehensive investigation of the ortho fluoro- and chloro- substituted benzoic acids both, as isolated molecules and in the crystalline phase. Quantum chemical calculations performed within the density functional theory (DFT) formalism are used to investigate the potential energy landscapes of the molecules, taking into special consideration the effects of the interactions between the carboxylic group and the ortho halogen substituents, as well as the nature of these later on the structure and properties of the investigated systems. The structures of the relevant conformers of the molecules are discussed in comparative terms, and used to rationalize experimental data obtained for the compounds in the gas phase and isolated in low-temperature inert matrices. The UV-induced photofragmentation reactions of two of the compounds isolated in cryogenic inert matrices were studied as illustrative cases. The structures of the crystals reported previously in the literature are revisited and discussed also in a comparative basis. Particular emphasis is given to the analysis of the intermolecular interactions in the different crystals, using Hirshfeld surface analysis, the CE-B3LYP energy decomposition model and the HOMA index, and to their correlation with thermodynamic data.
