In this study, the sinocalamus oldhami alkali lignin was depolymerized into phenolic products in a combined system by using the composite alkali and Ni-W2C/activated carbon (AC) as catalysts. FT-IR, GPC, TG, 2D-HSQC and GC-MS were used to analyze the composition, structure and distribution of degradation products, and the synergistic effect of metal and alkali catalysts on the depolymerization of lignin was also studied. The results showed that Ni-W2C/AC and composite alkali could effectively improve the catalytic degradation efficiency of lignin under mild conditions, 94.4% of lignin was converted and 17.18% of phenolic monomers were obtained under 260 degrees C for 5 h. In this composite system, the synergism of the basic sites, the metal active sites and the Lewis acid sites could promote the cleavage of C-O bonds in the lignin molecule and lower the char formation during the base-catalyzed solvolysis. Phenolic monomers were mainly composed of phenol, 2-methyl-phenol and p-cresol etc.

N-Alkylated 4-pyridones were obtained through a one-pot procedure involving either normal or interrupted Pummerer reactions between triflic anhydride-activated sulfoxides and 4-fluoropyridine derivatives, followed by hydrolysis. On the other hand, triflic anhydride-activated benzyl 6-fluoro-2-pyridyl sulfoxide could react with alkenes or alkynes to afford thiazolo[3,2-a]pyridin-5-ones, via the pyridinium salt intermediates.

A novel chiral nucleophilic organocatalyst easily synthesized from simple starting materials bearing a 5,6,7,8-tetrahydroimidazo[1,2-a]pyridine skeleton has been developed and successfully applied in the direct enantioselective C-acylation of 3-substituted benzofuranones. Its catalytic efficiency was shown to be comparable to that of the previously reported chiral 6,7-dihydro-5H-pyrrolo[1,2-a]imidazole catalyst. A wide range of 3,3-disubstituted benzofuranones, possessing a quaternary stereocenter, were synthesized with high yields and enantioselectivities.

In the presence of [p-cymene)RuCl2](2), (E)-configured alkenyl bromides couple with aromatic carboxylates to form orthovinylbenzoic acids. This C-H vinylation proceeds in high yields without any activating phosphine ligands and has an excellent functional group tolerance. Starting from commonly available (E/Z)-mixtures of alkenyl bromides, (E)-configured vinyl arenes or dienes are formed exclusively. Mechanistic studies show that this selectivity is achieved because the (E)configured alkenyl bromides undergo a smooth coupling, whereas the (Z)-isomers are rapidly eliminated with the formation of alkynes.

Herein we report a straightforward synthetic approach to 2,4,5-trisubstituted imidazoles from readily available primary alcohols using arene diruthenium(II) catalysts. Dinuclear arene ruthenium complexes have been synthesized and structurally characterized with the aid of analytical and spectral techniques. A library of 2,4,5-trisubstituted imidazoles was achieved with a yield up to 95% by loading 0.25 mol% of the catalyst. The present protocol is environmentally benign, which is performed under aerobic conditions and liberates water as the sole by-product.

This study investigates the active sites in natural organic matter (NOM) that are important for the removal of Cr (VI), by using Fe3O4 magnetic nanoparticles (MNPs) modified by NOM (Fe3O4@NOM). NaBH4 is used to selectively reduce carbonyl groups in Fe3O4@NOM MNPs to demonstrate the role of carbonyl structures in the reduction of Cr(VI), especially under irradiation. Results observed using NOM and low molecular weight compounds further demonstrated that carbonyl structures in Fe3O4@NOM MNPs, especially aromatic ketones, can strongly promote Cr(VI) reduction. This phenomenon corresponds well to a model in which charge transfer interactions occur between donors and acceptors in NOM.

Results: The antibacterial activities of the synthesized pyrazoles were evaluated against three gram-positive bacteria, such as Enterococcus durans, Staphylococcus aureus, Bacillus subtilis and two gram-negative bacteria such as Escherichia coli and Salmonella typhimurium. Conclusion: All the synthesized pyrazoles showed relatively high antibacterial activity against S. aureus strain, and none of them demonstrated antibacterial activity against E. coli.

Carbonyl allylation reactions constitute an important step in the formation of carbon-carbon reactions, and involve various related reactions that chiefly use allylmetal reagents. This report presents a nickel-catalyzed carbonyl allylation reaction using allyl acetate, which produces homoallyl alcohols in moderate to good yields, as an efficient methodology under reductive coupling conditions.

Agarwood is known to have a sedative effect and the less studied volatile aromatic constituents it contains may have contribution to the activity. In this study, two Kyara grade (highest-grade agarwood in Japan) samples were extracted using headspace-solid phase microextraction (HS-SPME) and analyzed through gas chromatography-mass spectrometry (GC-MS). Six low molecular weight aromatic compounds (LACs) and one structurally simple compound (diethylene glycol monoethyl ether) present in the aromas were individually evaluated for inhalational sedative activity in mice through open field test. Doses of 0.0001 g/L to 1 g/L were prepared for each compound and administered to mice (n = 6/dose/compound). Results revealed all compounds decreased spontaneous motor activity at almost all doses. Strongest sedative activity of each compound reduced total spontaneous motor activity by more than half against control, demonstrating their contribution to agarwood aroma and potential as independent sedating agents. Mixtures of compounds using their most effective dose were made and evaluated again for inhalational sedative effect. Interestingly, the combination of all compounds showed no significant effect and even caused stimulation in mice movements. This result suggests antagonistic-like interaction between the compounds, which is probably due to structural similarities. Consequently, it implies the other constituents present in agarwood, along with LACs, are also important to the overall sedative activity.

In current work, a class of novel 4,5-dihydro-1H-pyrazole-1-carboxylate derivatives (E01-E28) were designed, synthesized and evaluated. Among them, the most potent compound E24 exhibited comparable activity against a panel of cancer cells (GI(50) ranging 0.05-0.98 mu M) and tubulin polymerization inhibition (IC50 = 1.49 mu M) with reference drug CA-4(P) (GI(50) ranging 0.019-0.32 mu M, IC50 = 2.18 mu M). The following assays indicated that compound E24 disturbed the dynamics of tubulin catastrophe and rescue, which triggered G2/M arrest, leading to ROS accumulation, cleavage of PARP and apoptosis. Molecular dynamics simulation validated that compound E24 could tightly bind into tubulin heterodimers with beta Lys 254 and beta Cys 241 of tubulin in the docking pose. Metabolic stability and pharmacokinetics parameters were also determined. The half time (t(1/2)) displayed species differences in three microsomes. The plasma elimination half-life (t(1/2)), peak plasma concentration (C-max), mean retention time (MRT), the area under the curve (AUC(0-infinity),) and distribution volume (V-z) of E24 after intravenous administration were 0.90 +/- 0.22 h, 594.50 +/- 97.23 ng/mL, 1.09 +/- 0.22 h, 413.67 +/- 105.64 ng/mL*h and 5.03 +/- 1.82 L/kg, respectively. In HeLa-xenografts, compound E24 exhibited obvious antitumor efficacy via the suppression of tumor growth without weight loss of body or organ. In brief, compound E24 might be a hopeful candidate with excellent properties for oncotherapy as tubulin polymerization inhibitor. (C) 2018 Elsevier Masson SAS. All rights reserved.
