Three new N-heterocyclic carbene (NHC)-Pd(II) complexes using 5-phenyloxazole as the ancillary ligand have been obtained in moderate to good yields by a one-pot reaction of the corresponding imidazolium salts, palladium chloride and 5-phenyloxazole under mild conditions. Initial studies showed that one of the complexes is an efficient catalyst for the Buchwald-Hartwig amination of aryl chlorides with various secondary and primary amines under the varied catalyst loading of 0.01-0.05 mol%, thus it will enrich the chemistry of NHCs and give an alternative catalyst for the coupling of challenging while cost-low aryl chlorides.

Graphene oxide (GO)-catalyzed selective synthesis of amides via C-Sp3-H activation of methylarenes and consequent C-N bond formation with anilines under aqueous medium has been described. Oxygen functionality allied with GO surface played a dual role both as acid catalyst and oxidizing agent to some extent. However, GO has a copious effect on the reaction, shown by a high TOF value with TBHP as co-oxidant. The decisive role of carboxylic acid functional groups on GO nanosheets in this metal-free strategy has been confirmed and was monitored by various analytic techniques viz. Fourier transform-infrared, UV-Vis, Raman and XPS. A plausible mechanism was proposed by control experiments and by the isolation of the intermediate. Over-oxidation of methylarenes was not detected, and high recyclability of the carbocatalyst with its heterogeneous behavior facilitated the isolation and purification of the desired products. We have further explored the utility of this process for the chemoselective synthesis of benzimidazoles.

Activated biochar has been used in various areas, i.e., wastewater treatment. However, biochar contains volatile organic compounds, some of which are toxic organic pollutants that pose health risks to human. In this study, activated biochar was prepared by pyrolysis method using rice husks as raw materials and H2O as the activator. The volatile organic compound concentration of biochar before and after activation, as well as the adsorption characteristics of activated biochar, was investigated. The structure of the biochar was characterized by FTIR, SEM, and specific surface area analyzer. The results showed that activated biochar surface was mainly composed of carboxyl groups, and no phenolic hydroxyl or lactone groups formed during the process. In total, 54 volatile organic compounds were analyzed by a gas chromatography-mass spectrometer. The detection frequency of 45 volatile organic compounds reached 100%. The concentration of sum of these compounds was 93.26 and 110.62 mu g/g in the biochar before and after activation, respectively. Results of adsorption experiments showed that the adsorption and resolution of activated biochar to n-hexane were 29.33 and 5.4 mg/g, respectively. Compared to the biochar sample without activation, the activated biochar with the ratio of charcoal to water of 3:1 showed the best adsorption to n-hexane, whose surface area reached 351.23 m(2)/g.

Myeloid differentiation protein 2 (MD2) is a co-receptor of toll-like receptor 4 (TLR4) responsible for the recognition of lipopolysaccharide (LPS) and mediates a series of TLR4-dependent inflammatory responses in inflammatory lung diseases including acute lung injury (ALI). Targeting MD2 thus may provide a therapeutic strategy against these lung diseases. In this study, we identified a novel compound 4k with the potent anti-inflammatory activity among 39 methyl gallate derivatives (MGDs). MGD 4k exhibited a high binding affinity to MD2, which in turn prevented the formation of the LPS/MD2/TLR4 complex. In addition, MGD 4k significantly reversed the upregulation of LPS-induced inflammatory mediators such as tumor necrosis factor-alpha, interleukin-6, intracellular adhesion molecule-1, vascular cell adhesion molecule-1, and monocyte chemoattractant protein-1 in vitro and in vivo. Mechanistically, MGD 4k performed anti-inflammatory function by inactivating JNK, ERK and p38 signaling pathways. Taken together, our study identified MGD 4k as a novel potential therapeutic agent for ALI through inhibiting MD2, inflammatory responses, and major inflammation-associated signaling pathways.

Alternatives to the use of pressurized hydrogen (H-2) in chemical syntheses are of growing interest and importance in developing safer protocols. Ammonia borane (AB), with its high hydrogen content and ability to release H-2 under mild conditions, is one potential solution. However, optimization of AB dehydrogenation and further the use of AB as a H-2 source to facilitate tandem one-pot reactions with both high activity and stability is an ongoing research challenge. In this work, monodisperse AuPd nanoparticle (NP) catalysts were synthesized and systematically studied for AB dehydrogenation, and Au-rich NPs were found to be the most active composition for AB methanolysis with a turnover frequency (TOF) of 160 min(-1) surpassing most Pd-based NP catalysts to date. More importantly, Au-rich NPs were also active in the one-pot tandem reduction of a series of nitro-groups and the hydrodehalogenation of mono- and polyhalogenated persistent chemical pollutants under mild reaction conditions using only a 2:1 molar ratio of AB to substrate. The AuPd catalyst was stable after ten reaction runs for AB methanolysis and five reaction runs for tandem one-pot reactions without a loss of activity or change in NP structure and morphology.

Subunit-selective proteasome inhibitors are valuable tools to assess the biological and medicinal relevance of individual proteasome active sites. Whereas the inhibitors for the beta 1c, beta 1i, beta 5c, and beta 5i subunits exploit the differences in the substrate-binding channels identified by X-ray crystallography, compounds selectively targeting beta 2c or beta 2i could not yet be rationally designed because of the high structural similarity of these two subunits. Here, we report the development, chemical synthesis, and biological screening of a compound library that led to the identification of the beta 2c- and beta 2i-selective-compounds LU-002c (4; IC50 beta 2c: 8 nM, IC50 beta 2i/beta 2c: 40-fold) and LU-002i (5; IC50 beta 2i: 220 nM, IC50 beta 2c/beta 2i: 45-fold), respectively. Co-crystal structures with beta 2 humanized yeast proteasomes visualize protein-ligand interactions crucial for subunit specificity. Altogether, organic syntheses, activity-based protein profiling, yeast mutagenesis, and structural biology allowed us to decipher significant differences of beta 2 substrate-binding channels and to complete the set of subunit-selective proteasome inhibitors.

Chiral beta-amino alcohols are important building blocks for the synthesis of drugs, natural products, chiral auxiliaries, chiral ligands and chiral organocatalysts. The catalytic asymmetric beta-amination of alcohols offers a direct strategy to access this class of molecules. Herein, we report a general intramolecular C(sp(3))-H nitrene insertion method for the synthesis of chiral oxazolidin-2-ones as precursors of chiral beta-amino alcohols. Specifically, the ring-closing C(sp(3))-H amination of N-benzoyloxycarbamates with 2 mol% of a chiral ruthenium catalyst provides cyclic carbamates in up to 99% yield and with up to 99% ee. The method is applicable to benzylic, allylic, and propargylic C-H bonds and can even be applied to completely non-activated C (sp(3))-H bonds, although with somewhat reduced yields and stereoselectivities. The obtained cyclic carbamates can subsequently be hydrolyzed to obtain chiral beta-amino alcohols. The method is very practical as the catalyst can be easily synthesized on a gram scale and can be recycled after the reaction for further use. The synthetic value of the new method is demonstrated with the asymmetric synthesis of a chiral oxazolidin-2-one as intermediate for the synthesis of the natural product aurantioclavine and chiral beta-amino alcohols that are intermediates for the synthesis of chiral amino acids, indane-derived chiral Box-ligands, and the natural products dihydrohamacanthin A and dragmacidin A.

Background The side reactions of dehalogenation or C-N coupling tend to occur when halogenated aromatic amines are prepared by catalytic hydrogenation reduction of halogenated aromatic nitro compounds. In this paper, we prepared the sub-microspherical Fe3O4@PDA-Pd NPs catalyst apply it efficiently in the hydrogenation reduction of halogenated aromatic nitro compounds to prepare the halogenated aromatic amines under atmospheric pressure. The catalyst shows a high selectivity of greater than 96% and can effectively inhibit the occurrence of the side reactions of dehalogenation and C-N coupling. Results The optimum condition of the hydroreduction reaction is when tetrahydrofuran is used as solvent and the reaction happens at 50 degrees C for 5 h. The selectivity of the chlorinated aromatic amine and the fluorinated aromatic amine products exceed 99% and the yield exceeds 90%. Only a small amount of dehalogenated products and C-N coupling by-products were produced in the brominated aromatic compound and the iodinated aromatic compound. Conclusion We developed a promising method for preparing the superparamagnetic and strongly magnetic Fe3O4@PDA core-shell sub-microsphere-supported nano-palladium catalyst for catalyzing the hydrogenation reduction of halogenated aromatic nitro compounds. The halogenated aromatic amines were efficiently and highly selectively prepared under atmospheric pressure, with the side reactions of dehalogenation and C-N coupling effectively inhabited simultaneously.
