We report a mild palladium-catalyzed method for the selective allylation of 4-alkylpyridines in which highly basic pyridylic anions behave as soft nucleophiles. This method exploits alkylidene dihydropyridines, which are semi-stable intermediates readily formed using a ‘soft-enolization’ approach, in a new mechanistic manifold for decarboxylative allylation. Notably, the catalytic generation of pyridylic anions results in a substantially broader functional group tolerance compared to other pyridine allylation methods. Experimental and theoretical mechanistic studies strongly suggest that pyridylic anions are indeed the active nucleophiles in these reactions, and that they participate in an outer-sphere reductive elimination step. This finding establishes a new pK(a) boundary of 35 for soft nucleophiles in transition metal-catalyzed allylations.

A series of two new mono- and one binuclear m-nitrato bridged copper(II) complexes [Cu(L)(HL)]ClO4 (1), [Cu(HL)(NO3)(H2O)](2)NO3 center dot H2O (2) and [Cu-2(L-2)(mu-NO3)(2)] (3), with an unsymmetrical NNO donor Schiff base (HL) have been synthesized and characterized by elemental analysis, FTIR, CV, UV-vis and EPR spectroscopy. Their molecular structures were also determined by single crystal X-ray crystallography. In the binuclear complex 3, the Cu center dot center dot center dot Cu distance is 3.494 angstrom. In 1, 2 and 3, the Cu(II) centers have distorted square pyramidal geometry (tau(5) = 0.05-0.17). Evidence of weak pi center dot center dot center dot pi stacking intermolecular interactions along with other non-covalent interactions (hydrogen bonding) was observed by analyzing the respective crystal structures of the complexes. Thus, these hydrogen bonds, pi center dot center dot center dot pi stacking interactions and other weak intermolecular interactions establish in the form of supramolecular architectures a crystalline network environment. The non-covalent interactions were also investigated by employing Hirshfeld Analysis. The room temperature magnetic moments of the mononuclear complexes are less than the spin only values which are indicative of small interactions. Also, significant magnetic interactions were not exhibited by binuclear copper(II) complex 3 in the variable temperature magnetic measurements. The X-band EPR spectra of all three complexes exhibit copper(II) hyperfine structures as well as zero-field splitting which are appropriate for the triplet states of dimers. In complexes 1 and 2, the presence of pseudo dipolar interactions is proposed. Quantum chemical calculations (DFT) were carried out on complexes 1-3 to explore the electronic and spectral properties of these newly synthesized complexes. These complexes show significant antiproliferative and SOD activity. The SOD activity measured in terms of kMcCF is in the range 4.94-12.31 (mol L)(-1)s(-1))x 10(4). (C) 2021 Elsevier Ltd.

Fermented soy sauce is used worldwide to enhance the flavour of many dishes. Many types of soy sauce are on the market, and their differences are mostly related to the country of origin, the production process applied and the ratio of ingredients used. Consequently, several aromas, tastes, colours, and textures are obtained. Nowadays, soy sauce can also be produced without microorganisms making the process shorter and cheaper. However, flavour may be lost. We have carried out a comprehensive metabolomics analysis of volatile compounds using stir bar sorptive extraction (SBSE)-GC-MS to relate differences in volatile content to production history and origin. The results revealed major differences between fermented and non-fermented soy sauces, and a list of volatile compounds is reported as being characteristic of each type. This study was able to relate volatiles to the production process using SBSE-GC-MS and to aroma characteristics using GC-O-MS.

A pyrimidine moiety exhibiting a wide range of pharmacological activities has been employed in the design of privileged structures in medicinal chemistry. To prepare libraries of novel heterocyclic compounds with potential biological activities, a series of novel 2-(pyridin-2-yl) pyrimidine derivatives were designed, synthesized and their biological activities were evaluated against immortalized rat hepatic stellate cells (HSC-T6). Fourteen compounds were found to present better anti-fibrotic activities than Pirfenidone and Bipy55 ‘ DC. Among them, compounds ethyl 6-(5-(p-tolylcarbamoyl)pyrimidin-2-yl)nicotinate (12m) and ethyl 6-(5-((3,4-difluorophenyl)carbamoyl)pyrimidin-2-yl)nicotinate (12q) show the best activities with IC50 values of 45.69 mu M and 45.81 mu M, respectively. Furthermore, the study of anti-fibrosis activity was evaluated by Picro-Sirius red staining, hydroxyproline assay and ELISA detection of Collagen type I alpha 1 (COL1A1) protein expression. Our study showed that compounds 12m and 12q effectively inhibited the expression of collagen, and the content of hydroxyproline in cell culture medium in vitro, indicating that compounds 12m and 12q might be developed the novel anti-fibrotic drugs.

Functionalization with C1-building blocks are key synthetic methods in organic synthesis. The low reactivity of the most abundant C-1-molecule, carbon dioxide, makes alternative carboxylation reactions with CO2-surrogates especially important. We report a photoredox-catalyzed protocol for alkene carbamoylations. Readily accessible 4-carboxamido-Hantzsch esters serve as convenient starting materials that generate carbamoyl radicals upon visible light-mediated single-electron transfer. Addition to various alkenes proceeded with high levels of regio- and chemoselectivity.

A series of bidendate pyridine-functionalized metal N-heterocyclic carbene (NHC) complexes with various wingtip substituents (R = methyl, phenyl and tert-butyl) had been prepared from silver oxide-mediated transmetalation method. The basic backbone of the NHC ligands were prepared in two step-wise reactions: reduction of the commercially available 2-benzoylpyridine, followed by halogenation to yield 2-(chloro(phenyl) methyl) pyridine. Subsequent reactions with different imidazoles gave the desired imidazolium salts (or NHC precursors) with different R groups at the N wingtip (R = Me, Ph, t-Bu). Transmetalation of the imidazolium salts into platinum NHC complexes were achieved by using Ag2O mediated method with Pt(cod)Cl-2 as the transmetalating agent. On the other hand, nickel NHC complexes were obtained via one pot synthesis method with nickel chloride as the transmetalating agent and reflux in the presence of a base. Following recrystallisation, the molecular structure of Pt NHC complex (+/-)-5a had been successfully elucidated via single crystal X ray diffraction (XRD) analysis. The six-membered ring of the platinum NHC complexes adopted a boat conformation with the phenyl ring arranged at the axial position. Meanwhile, two unexpected nickel complexes, i.e. a simple nickel coordination complex and a nickelate complex, were obtained and studied using XRD. These Pt NHC complexes and unexpected Ni complexes were evaluated for their in vitro antimicrobial and anticancer activities against a panel of pathogenic microorganisms and three selected human cancer cell lines, including breast (MCF7), colon (HCT116) and oral (H103) cancer cells. Generally, the Pt NHC complexes displayed enhanced antimicrobial activities upon coordination to metals, as compared to the corresponding imidazolium salts i.e. NHC precursors, with minimum inhibitory concentration (MIC) values in micromolar (mM) range. A couple of platinum NHC complexes synthesized exhibited antimicrobial activities with MIC as low as 2 mM, which are comparable to silver NHC complexes with renowned antimicrobial profiles. Similarly, upon coordination to the metals, the cytotoxic effects of the platinum NHC complexes increased significantly as compared to the imidazolium salts. Among all, platinum NHC complex (+/-)-5c displayed significant cytotoxicities towards the cancer cells with IC50 values that are two to three times lower than that of the anticancer drug cisplatin. In summary, evidences for influence of both wingtip substituents and metals on the biological activities of the complexes have been found. (C) 2019 Elsevier B.V. All rights reserved.
