A practical heterogeneous palladium-catalyzed carbonylative Suzuki coupling of aryl iodides with arylboronic acids under carbon monoxide gas-free conditions has been developed using a bidentate phosphino-functionalized magnetic nanoparticle-immobilized palladium(II) complex as catalyst. Formic acid was utilized as the carbon monoxide source with dicyclohexylcarbodiimide as the activator, and a wide variety of biaryl ketones were generated in moderate to high yields. The new heterogeneous palladium catalyst can be prepared via a simple procedure and can easily be separated from a reaction mixture by simply applying an external magnet and recycled up to 10 times without any loss of activity.

New five-membered oxazol-2(3H)-one heterocycles and 1,2-diaroylhydrazines are obtained in good yield when 1,2-dicarbonyl substrates are reduced at the cathode in N-methyl formamide/LiClO4 as solvent-supporting-electrolyte system, and in the presence of arenediazonium salts. Electrochemical pathways are presented to involve a) cascade reactions: hydrogen atom abstraction from a solvent molecule, radical coupling reaction with substrate intermediate, and intramolecular migration of a methylamino group, to provide oxazolones or b) surprising C-C bond cleavage in the substrate radical anion, assisted by a diazonium salt, that evolves to disubstituted arylhydrazides.

A selective, economical, and ecological protocol has been described for the oxidation of methyl arenes and their analogs to the corresponding carbonyl compounds and epoxidation reactions of alkenes with molecular oxygen (O-2) or air as a green oxygen source, under mild reaction conditions. The nano Ni/g-C3N4 exhibited high photocatalytic activity, stability, and selectivity in the C-H activation of methyl arenes, methylene arenes, and epoxidation of various alkenes under visible- light irradiation without the use of an oxidizing agent and under base free conditions.

Asymmetric reduction studies of heteroaryl ketones, including phenyl(pyridin-2-yl)methanone in enantioselective form with biocatalysts are very few, and chiral heteroaryl alcohols have been synthesized generally in the small scale. In this study, seven bacterial strains have been used to produce the (S)-phenyl(pyridin-2-yl)methanol in high enantiomeric excess and yield. Among the tested strains, Lactobacillus paracasei BD101, was found to be the best biocatalyst for the reducing phenyl(pyridin-2-yl)methanone to the (S)-phenyl(pyridin-2-yl)methanol at gram scale. The asymmetric bioreduction conditions were systematically optimized using L. paracasei BD101, which demonstrated excellent enantioselectivity and high level of conversion for the bioreduction reaction. (S)-phenyl(pyridin-2-yl)methanol, which is an analgesic, was produced enantiomerically pure form in the first time on gram scale using a biocatalyst. In total, 5.857 g of (S)-phenyl(pyridin-2-yl)methanol in enantiomerically pure form (>99% enantiomeric excess) was obtained in 52 h with 93% yield using whole cells of L. paracasei BD101. Enantiomerically pure (S)-phenyl (pyridin-2-yl)methanol, which is an analgesic, was first produced in the gram scale using a biocatalyst with excellent ee (>99%) and yield (93%). [GRAPHICS] .

Two diastereoisomers of bis(2-benzoylpyridine-O,N)dichloridonickel(II) have been isolated from the reactions of nickel(II) chloride hexahydrate and the organic ligand depending on the reaction solvent (ethanol, acetonitrile) used. DFT studies indicate that one of the isomers is more stable in both solvents, but nevertheless different diastereoisomers are crystallized from the two solvents. The two complexes represent the first pair of well characterized diastereoisomers in the coordination chemistry of 2-pyridyl ketones, providing a new example in the chemistry of octahedral MA(2)(BC) over cap (2) complexes (A = a monodentate ligand, (BC) over cap = an unsymmetrical bidentate chelate).

N-(Pyrid-2-yl)-substituted azolium and pyridinium salts, precursors for hybrid NHC-containing ligands, were obtained with excellent regioselectivity, employing a deoxygenative CH-functionalization of pyridine-N-oxides with substituted imidazoles, thiazoles, and pyridine. Unlike the traditional SNAr-based methods, this approach provides high yields for substrates bearing substituents of different electronic nature. The utility of azolium and pyridinium salts thus prepared was also highlighted by the synthesis of pyridyl-substituted imidazolyl-2-thione, benzodiazepine as well as 2-aminopyridines.

A metal-free access to 2-iodo-1,3-disubstituted indolizines has been developed. The proposed synthesis is relatively simple and efficient and involves the iodine-triggered 5-endo-trig cyclization of 2-pyridylallene precursors. While it can be conducted on a gram scale, the preparation of the precursors is straightforward and does not always require intermediate purifications. The obtained 2-iodoindolizines can be further functionalized through cross-coupling reactions.

P-glycoprotein (P-gp)-mediated multidrug resistance (MDR) is a major obstacle to successful chemotherapy for leukemia. In this study, a series of thiosemicarbazone-containing compounds (4a-b, 7a-q) were synthesized. Biological evaluation showed that the most active compound 7e displayed potent anti-leukemia activity against P-gp overexpressing drug-resistant K562/A02 cells, with an IC50 value of 0.44 mu M. Notably, compound 7e exhibited a selective killing effect on K562/A02 cells by dose-dependently increasing the intracellular levels of reactive oxygen species (ROS), thus exerting a potential collateral sensitivity (CS)-promoting effect in vitro. Moreover, compound 7e could inhibit HDAC1 and HDAC6, and induce the apoptosis of K562/A02 cells by increasing the expression of Bax, decreasing Bcl-2 protein level, and promoting the cleavage of caspase-3 and PARP, respectively. Overall, 7e may be a potential anti-cancer agent against drug-resistant myelogenous leukemia.

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.

Tetrabutylammonium hydroxide (TBAOH) was discovered as a highly efficient and green catalyst for aerobic oxidation of the -methylene carbon of primary amines as well as benzylic groups into the corresponding amides and ketones under neat conditions. We described herein, ionic liquid TBAOH catalysed aerobic oxidation of benzyl amines to benzamides and with elemental sulfur; the corresponding benzylbenzothioamides were obtained under metal-free, oxidant-free and base-free conditions. Applicability at the gram scale for the synthesis of the desired amides/ketones is also demonstrated with the present protocol.
