The catalytic activity of tris(3,4,5-trifluorophenyl)borane has been explored in the 1,2-hydroboration reactions of unsaturated sub-strates. Under conventional conditions, the borane was found to be active only in the hydroboration of aldehyde, ketone and imine substrates, with alkenes and alkynes not being reduced effectively. The use of microwave irradiation on the other hand has permitted alkenes and alkynes to be hydroborated in good yields.

A new M6L3 metal-organic triangular prism host Co-L-1 was synthesized that contains a sufficiently large cavity for encapsulation of a quinhydrone (QHQ) electron transporter to form charge-transfer complexes for accelerating electron delivery. Through the strong coordinating ability of the ONP chelator, a suitable redox potential was obtained for the combination of light-driven proton reduction with the selective hydrogenation of nitro groups. The experimental results showed that the regulation of redox potential is very beneficial for hydrogen production and that the introduction of QHQ accelerates electron transfer and increases the reaction rate. Control experiments based on an inhibitor and a mononuclear compound resembling the cobalt corner of the triangular prism suggest enzyme-like behaviour. This synthetic platform, in which the supramolecular systems exhibit high activity and stability, provides an alternative strategy to selectively hydrogenate nitroarenes using light as a clean energy source.

A novel method was developed for the synthesis of substituted carbazoles from commercially available starting materials under metal-free conditions. This strategy involves a [1s,6s] sigmatropic shift step and introduces an electron-withdrawing ester substituent at the C2 position of the carbazole ring. The present protocol afforded the desired carbazole derivatives with good regioselectivity and well functional group tolerance. DFT calculations were carried out to support the reaction pathway.

Direct C(sp3)-H functionalization of alkyl nitriles is a low toxic and facile route to nitrile-containing compounds. In this research, the Ag2CO3-mediated nitrile methylenation of enol acetates is developed to prepare gamma-ketonitriles through the direct C(sp(3))-H oxidative functionalization of acetonitrile. A radical pathway is proposed, and acetonitrile serves both as solvent and CN-containing radical source. (C) 2019 Elsevier Ltd. All rights reserved.

Selective oxidation of olefin derivatives to ketones has made innovative development over palladium(0) supported on reduced graphene oxide. Compared to traditional Wacker oxidation, the novel method offers an economical and environment-friendly option by using graphene oxide (GO) as a ‘solid weak acid’ instead of classical homogeneous catalysts like H2SO4 and CF3COOH. X-ray diffraction, X-ray photoelectron spectroscopy, scanning electron microscope and transmission electron microscopy images of Pd degrees/RGO showed that the nanoscaled Pd particles generated at the flake structure of reduced graphene oxide. Under optimized condition, up to 44 kinds of ketones with different structures can be prepared with excellent yields.

Indoleamine 2,3-dioxygenase 1 (IDO1) and tryptophan 2,3-dioxygenase (TDO) are constitutively overexpressed in many types of cancer cells and exert important immunosuppressive functions. In this article, a series of 4,6-substituted-1H-indazole derivatives were synthesized and evaluated the inhibitory activities against IDO1 and TDO, as well as their structure-activity relationships (SARs). Among these, compound 35 displayed the most IDO1 inhibitory potency with an IC50 value of 0.74 mu M in an enzymatic assay and 1.37 mu M in HeLa cells. Quantitative analysis of the Western blot results indicated that 35 significantly decreased the INF gamma-induced IDO1 expression in a concentration-dependent manner. In addition, 35 showed promising TDO inhibition with an IC50 value of 2.93 mu M in the enzymatic assay and 7.54 mu M in A172 cells. Moreover, compound 35 exhibited in vivo antitumor activity in the CT26 xenograft model. These findings suggest that 1H-indazole derivative 35 is a potent IDO1/TDO dual inhibitor, and has the potential to be developed for IDO1/TDO-related cancer treatment.

A simple and efficient continuous flow methodology has been developed for hydrogenation and reductive deuteration of nitriles to yield primary amines and also valuable alpha,alpha-dideutero analogues. Raney nickel proved to be a useful catalyst for the transformation of a wide range of nitriles under reasonably mild conditions with excellent deuterium incorporation (>90 %) and quantitative conversion. Among known model compounds, three new deuterated primary amines were prepared. The large-scale synthesis of deuterated tryptamine was also carried out to deliver 1.1 g product under flow conditions.

A novel 2-thiopyrimidine/chalcone hybrid was designed, synthesised, and evaluated for their cytotoxic activities against three different cell lines, K-562, MCF-7, and HT-29. The most active cytotoxic derivatives were 9d, 9f, 9n, and 9p (IC50=0.77-1.74 mu M, against K-562 cell line), 9a and 9r (IC50=1.37-3.56 mu M against MCF-7 cell line), and 9a, 9l, and 9n (IC50=2.10 and 2.37 mu M against HT-29 cell line). Compounds 9a, 9d, 9f, 9n, and 9r were further evaluated for their cytotoxicity against normal fibroblast cell line WI38. Moreover, STAT3 and STAT5a inhibitory activities were determined for the most active derivatives 9a, 9d, 9f, 9n, and 9r. Dual inhibitory activity was observed in compound 9n (IC50=113.31 and 50.75 mu M, against STAT3 and STAT5a, respectively). Prediction of physicochemical properties, drug likeness score, pharmacokinetic and toxic properties was detected.

This paper reports the first example of dearomatization of ubiquitous terpyridine (tpy) ligands via 2’/6′-, 3/5′-, or 4′-selective alkylation of the central pyridine ring. The reaction is mediated by the most abundant metal in the Earth’s crust, aluminum (Al), and depending on the conditions employed, exhibits ionic or radical character as suggested by experimental and computational analysis. In the latter case, intermediate formation of an Al-III complex supported by pi-radical monoanionic ligand (tpy(center dot))(1-) is apparent. The 3’/5′-alkylation leads to unprecedented zwitterionic Meisenheimer Al-III complexes, which were identified as efficient precatalysts for the selective hydroboration of C=O and C equivalent to C functionalities. Turnover numbers (TONs) up to similar to 1000 place the corresponding complexes in the category of the most efficient Al catalysts reported to date for the title reaction. The acquired data suggest that aluminum monohydrides, or more likely dihydrides, could be relevant catalytic species. Alternatively, one can also imagine a mechanistic scenario in which the dearomatized chemically noninnocent ligand acts as hydride donor, and a detailed investigation of this is warranted in the future.

Uniform dispersion of ultrafine spherical silver nanoparticles (NPs) was obtained over the surface of Fe3O4@SiO2@KIT-6 core-shell support via functionalization of the mesoporous KIT-6 shell by aminopropyltriethoxysilane, followed by coordination of Ag+ ions and in situ chemical reduction with sodium borohydride. The obtained hybrid material, Fe3O4@SiO2@KIT-6-Ag nanocomposite, was fully characterized by Fourier transform infrared spectroscopy, X-ray diffraction, scanning electron microscopy, and transmission electron microscopy, and used as an efficient catalyst for selective reduction of nitroaromatic compounds in aqueous solution at ambient temperature and neutral pH [nine examples, apparent rate constants at 25 degrees C, k (min(-1)), 0.112-0.628]. As a non-aromatic example, nitrofurazone which is a cytotoxic antibiotic was also reduced selectively at nitro group without reduction of other functionalities. Fe3O4@SiO2@KIT-6-Ag NPs also showed potential ability to act as catalyst for reduction of nitromethane in aqueous solution which can provide a colorimetric method for detection of nitromethane in solution down to 0.9×10(-4)molL(-1). Fe3O4@SiO2@KIT-6-Ag nanocomposite was also screened for its antibacterial activity, and satisfactory results were obtained in comparison with drug references including Tetracycline, Chloramphenicol and Cefotaxime as positive controls, on gram negative Escherichia coli and Pseudomonas aeroginosa. Ease of recycling of the Fe3O4@SiO2@KIT-6-Ag is another benefit of this nanocatalyst. Under the optimized conditions, the recycled catalyst showed 15% loss of efficiency after five successive runs.
