Herein we report the synthesis and application of a versatile class of N-heterocyclic carbene ligands based on an imidazo[1,5-a]pyridine-3-ylidine backbone that is fused to a chiral oxazoline auxiliary. The key step in the synthesis of these ligands involves the installation of the oxazoline functionality via a microwave-assisted condensation of a cyano-azolium salt with a wide variety of 2-amino alcohols. The resulting chiral bidentate NHC-oxazoline ligands form stable complexes with rhodium(I) that are efficient catalysts for the enantioselective hydrosilylation of structurally diverse ketones. The corresponding secondary alcohols are isolated in good yields (typically >90%) with good to excellent enantioselectivities (80-93% ee). The reported hydrosilylation occurs at ambient temperatures (40 degrees C), with excellent functional group tolerability. Even ketones bearing heterocyclic substituents (e.g., pyridine or thiophene) or complex organic architectures are hydrosilylated efficiently, which is discussed further in this report.

The Noyori-Ikariya (arene)Ru(II)/TsDPEN precatalyst has been anchored to amorphous silica and DAVISIL through the eta(6)-coordinated arene ligand via a straightforward synthesis and the derived systems, (arene)Ru(II)/TsDPEN@silica and (arene)Ru(II)/TsDPEN@DAVISIL, form highly efficient catalysts for the asymmetric transfer hydrogenation of a range of electron-rich and electron-poor aromatic ketones, giving good conversion and excellent ee’s under mild reaction conditions. Moreover, catalyst generated in situ immediately prior to addition of substrate and hydrogen donor, by reaction of silica-supported [(arene)RuCl2](2) with (S,S)-TsDPEN, was as efficient as that generated from its preformed counterpart [(arene)Ru{(S,S)-TsDPEN}Cl]@silica. Gratifyingly, the initial TOFs (up to 1085 h(-1)) and ee’s (96-97 %) obtained with these catalysts either rivalled or outperformed those previously reported for catalysts supported by either silica or polymer immobilized through one of the nitrogen atoms of TsDPEN. While the high ee’s were also maintained during recycle studies, the conversion dropped steadily over the first three runs due to gradual leaching of the ruthenium.

Transition-metal-catalyzed C-H activation synthesis of heterocyclic spiro[4,4]nonanes has persistently witnessed the use of additional stoichiometric transition-metal oxidant when employing C=C bond as the Spiro ring closure site. Herein, we have addressed the issue by reporting a redox-neutral strategy for spiro[indene-1,4′-oxa-zolidinones] synthesis via Rh(III)-catalyzed coupling of 4-phenyl-1,3-oxazol-2(3H)-ones with alkynes. The synthesis features a broad substrate scope and high regiospecificity.

The starting precursors 2-carbohydrazides, bearing thienopyridine moiety, were prepared using 2-thioxopyridine-3-carbonitriles as key synthons. Next, 2-carbohydrazides were reacted with a variety of 4-substituted benzylidinemalononitriles or 4-substituted benzaldehydes to afford a new series of the target hydrazones incorporating thienopyridine moiety. The elemental analyses and spectral data were used to demonstrate the structures of new hydrazones series. The in vitro antibacterial activities of the target hydrazones were evaluated against different strains of Gram-positive and Gram-negative bacteria. In comparison with chloramphenicol as a reference drug, hydrazones 13b, 13c and 13d, linked to p-C1, p-Br and p-Me moiety, respectively, exhibited the strongest activities against all tested bacteria with MIC values in the range of 6.2-12.5 mu g/mL. In addition, several new hydrazones were tested as in vitro cytotoxic agents against each of human breast carcinoma MCF-7 cell line, colon cancer Caco2 cell line and liver hepatocellular carcinoma HEPG2 cell line. The hydrazones 13b, 13c and 13d demonstrated the best cytotoxicity against the tested eukaryotic cells. Furthermore, both experimental and docking studies could predict the promising inhibitory activities of hydrazones 13c and 13d against COX-2 enzyme with IC 50 of 0.110 and 0.104 mu M, respectively, when compared with Celecoxib (IC50 of 0.115 mu M).

A novel metal-free catalytic one-pot approach has been developed for the esterification of aralkyl ketones with alcohols under open-air atmospheric conditions. The inexpensive iodide/oxone reagent system allowed the cascade C(sp(3))-H bond oxygenation, selective C-C bond cleavage and esterification through the both radical and ionic pathways in a stepwise manner in one-pot. This mild, convenient and economically viable catalytic method tolerates the various functional groups to provide the corresponding alkyl benzoates in up to 98% yields with up to 99% selectivity. The efficiency and feasibility of scale-up of the present catalytic system was demonstrated with gram scale experiments (up to 10 gram scale).

CuMgAl layered double hydroxide compounds (CuMgAl-LDHs) have been synthesized, characterized and in-vestigated in the aerobic CDC reactions. The results indicated that NH3 center dot H2O coprecipitated CuMgAl LDH (N-CuMgAl-LDH) was able to efficiently accelerate the CDC reactions between the alpha-Csp(3)-H of N-aryltetrahy-droisoquinolines and nucleophiles. A wide scope of N-aryltetrahydroisoquinoline analogues and nucleophiles with different C-H bonds (C-sp3-H, C-sp2-H and Csp-H) could be tolerated by the N-CuMgAl-LDH system. Compared with the sample using Na2CO3 as the precipitant (C-CuMgAl-LDH), N-CuMgAl-LDH showed higher catalytic activity, which probably was due to its higher surface acidity. Dual function of redox and acidity for the N-CuMgAl-LDH catalyst has been observed in the CDC reaction. According to the obtained catalytic results, kinetic isotope effect experiment and XPS analysis, iminium ion was proposed as the key intermediate, made possible by the cycle of Cu2+ and Cu+ under the aerobic conditions.

Twelve new chiral chelating resins have been prepared using solid phase organic synthesis with the Merrifield and Wang resins and the bidentate amine 1,2-ethylenediamine, followed by the coupling of asymmetric ketones such as 1-phenyletanone, 4-methyl-2-pentanone 4-nitroacetophenone and 4-methoxyacetophenone to form prochiral imines. The enantioselective reduction with borane and (R)-(+)-2-Methyl-CBS-oxazaborolidine leads to the chiral resins with yields greater than 86%. We used these chiral resins to prepare 24 reducing complexes with alkali tetrahydroborates in a very simple way giving yields greater than 87%. Finally, we achieved a preliminary enantioselective reduction of acetophenone employing the Merrifield’s chiral chelating resins obtaining the corresponding S alcohol in a 70:30 ratio with the R analog alcohol.

Membrane-bound pyrophosphatases (mPPases) regulate energy homeostasis in pathogenic protozoan parasites and lack human homologues, which makes them promising targets in e.g. malaria. Yet only few nonphosphorus inhibitors have been reported so far. Here, we explore an isoxazole fragment hit, leading to the discovery of small mPPase inhibitors with 6-10 mu M IC50 values in the Thermotoga maritima test system. Promisingly, the compounds retained activity against Plasmodium falciparum mPPase in membranes and inhibited parasite growth.

A new diamine bearing flexible ether, rigid pyridine, and bulky anthrone pendent group, 10,10-bis[4-(4-amino-2-pyridinoxy)phenyl]-9(10H)-anthrone (BAPPA), was prepared in three steps from anthrone. BAPPA was reacted with six conventional aromatic dianhydrides in N, N-dimethylacetamide (DMAc) to form the corresponding new poly(ether imide)s (PEIs) via the poly(ether amic acid) (PEAA) precursors with inherent viscosities ranging from 0.85 dL g(-1) to 1.26 dL g(-1) and thermal imidization. All the PEAAs could be cast from DMAc solution and thermally converted into transparent, flexible, and tough PEI films with tensile strength of 72.2-112.4 MPa, tensile modulus of 1.8-2.1 GPa, and elongation at break of 10-18%. These PEIs were predominantly amorphous and displayed excellent thermal stability with the glass transition temperature of 290-388 degrees C, the 5% weight loss temperature of 480-514 degrees C, and the residue of 68-43% at 800 degrees C in nitrogen. The PEIs derived from 1,4-bis(3,4-dicarboxyphenoxy)benzene dianhydride and 4,4 ‘-hexafluoroisopropylidenediphathalic anhydride exhibited excellent solubility in organic solvents such as N-methyl-2-pyrrolidinone, DMAc, N, N-dimethylformamide, pyridine, and even in tetrahydrofuran. Meanwhile, these PEIs also exhibited high optical transparency with the ultraviolet cutoff wavelength in the 374-427 nm range and the wavelength of 80% transparency in the range of 468-493 nm.
