Phenols are common precursors and core structures of a variety of industrial chemicals ranging from pharmaceuticals to polymers. However, the synthesis of site-specifically substituted phenols is challenging, and thus the development of new methods for this purpose would be highly desirable. Reported here is a protocol for palladium-catalyzed ortho-selective alkylation reactions of phenols with primary alcohols by a dearomatization-rearomatization strategy, with water as the sole by-product. Various substituted phenols and primary alcohols were compatible with the standard reaction conditions. The detailed mechanism of this transformation was also investigated.

BackgroundLaminitis is a common and serve disease which caused by inflammation and pathological changes of the laminar junction. However, the pathologic mechanism remains unclear. In this study we aimed to investigate changes of the gut microbiota and metabolomics in oligofructose-induced laminitis of horses.ResultsAnimals submitted to treatment with oligofructose had lower fecal pH but higher lactic acid, histamine, and Lipopolysaccharide (LPS) in serum. Meanwhile, oligofructose altered composition of the hindgut bacterial community, demonstrated by increasing relative abundance of Lactobacillus and Megasphaera. In addition, the metabolome analysis revealed that treatment with oligofructose decreased 84 metabolites while 53 metabolites increased, such as dihydrothymine, N3,N4-Dimethyl-L-arginine, 10E,12Z-Octadecadienoic acid, and asparagine. Pathway analysis revealed that aldosterone synthesis and secretion, regulation of lipolysis in adipocytes, steroid hormone biosynthesis, pyrimidine metabolism, biosynthesis of unsaturated fatty acids, and galactose metabolism were significantly different between healthy and laminitis horses. Furthermore, correlation analysis between gut microbiota and metabolites indicated that Lactobacillus and/or Megasphaera were positively associated with the dihydrothymine, N3,N4-Dimethyl-L-arginine, 10E,12Z-Octadecadienoic acid, and asparagine.ConclusionsThese results revealed that disturbance of gut microbiota and changes of metabolites were occurred during the development of equine laminitis, and these results may provide novel insights to detect biomarkers for a better understanding of the potential mechanism and prevention strategies for laminitis in horses.

Ruthenium complexes are currently significant attention in medicinal chemistry as they offer various properties which make them an appropriate choice for drug development. Herein, a series of ruthenium(II)-p-cymene-2aryl-imidazo-1,10-phenanthroline derivatives have been prepared and characterised by elemental analysis, infrared, LC-mass and NMR techniques. The structural and chemical properties shows that Ru(II) complexes have got rigidity, planarity, aromaticity, hydrogen donating and accepting capability which aids both solubility and interaction with biomolecules. The binding strength of these complexes with DNA and BSA were found to be 10(4)-10(6) M-1. The competitive displacement of ethidium bromide (EtBr) from DNA in the presence of complex reveals an intercalation or groove binding further this was supported by viscosity and in-silico studies. The cytotoxicity study of these Ru(II) complexes were conducted with two cancer cell lines (MDA-MB-231 and HeLa) and one human embryonic kidney cells (HEK-293). The study revealed that [(eta(6)-p-cymene)RuCl (kappa(2)-N,N-2-(4-fluorophenyl)-1H-imidazo[4,5-f][1,10]Phenanthroline]center dot PF6 (4e), [(eta(6)-p-cymene)RuCl(kappa(2)-N,N-2-(4-bromophenyl)-1H-imidazo[4,5-f][1,10]Phenanthroline]center dot PF6 (4f) and [(eta(6)-p-cymene)RuCl(kappa(2)-N,N-2-(4-nitrophenyl)1H-imidazo[4,5-f][1,10]Phenanthro line]center dot PF6 (4g) were found exhibit least inhibitory concentration (IC50) and high selectivity with respect to HeLa and MDA-MB-231. The activity of the Ru(II) complexes were position and substituents dependent.

A facile and general method for constructing carbon-heteroatom (C-P, C-O, C-S, and C-N) bonds via C-N cleavage of benzyl ammonium salts under transition-metal-free conditions was reported. The combination of t-BuOK and 18-crown-6 enabled a wide range of substituted benzyl ammonium salts to couple readily with different kinds of heteroatom nucleophiles, i.e. hydrogen phosphoryl compounds, alcohols, thiols, and amines. Good functional group tolerance was demonstrated. The scale-up reaction and one-pot synthesis were also successfully performed.

Bio-oils after hydrotreatment can still contain significant amount of phenols and cyclic olefins as the products of an incomplete deoxygenation. The removal of these compounds would be necessary to produce suitable components for automotive fuels. However, no routine method currently exists for the reliable determination of these groups in hydrotreated bio-oils (HBOs). In this paper, we analyzed 140 different pure oxygenates as model compounds using the bromine number method (ASTM D1159) observing that most compounds present in HBOs react with one equivalent of bromine. The determination of phenols using bromine number method in crude biooil is complicated especially by the presence of guaiacols and syringols that react with more than one equivalent of bromine and, thus, the obtained result is significantly overestimated. Further we optimized the chromatographic separation of hydrocarbons from HBOs for the selective determination of olefins content. As no other reactive compounds under the conditions of the method, besides phenols and olefins, were observed in HBOs, the difference between HBO bromine number (before hydrocarbons separation) and olefins content correspond to the total amount of phenols. The method was finally applied to 11 HBOs with different content of oxygen, providing a good correlation between phenols and oxygen content.

Nature is abundant with multi-functional and efficient catalysts such as redox enzymes which scientists wish to emulate with synthetic catalysts. One approach is to tune molecular catalysts through metal-organic ligands but there are grand challenges of molecular catalysts for real applications in energy field. Here we demonstrate a robust inorganic construct based on metal-metal oxide-carbon triple junction nanostructures (ZrO2/Pd/carbon) that mimics the functions of enzymes for highly efficient proton transport. The metal oxide tunes the local acidic environment of the metal and improves its ability for proton transport, efficient adsorption of substrate, and accelerated electron transfer. Using electrocatalytic hydrogenation (ECH) of benzaldehyde as a model reaction, we show that the intrinsic activity of the metal toward hydrogenation reaction is improved by over 200 % on the triple junction nanostructured catalysts. This study demonstrates the potential of rational design of multicomponent nanostructured catalysts to achieve enzyme like properties in synthetic catalysts.

In this study, a series of mono- and diallylphenol derivative were designed, synthesized, and evaluated as potential human 15-lipoxygenase-1 (15-hLOX-1) inhibitors. Radical scavenging potency of the synthetic allylphenol derivatives was assessed and the results were in accordance with lipoxygenase (LOX) inhibition potency. It was found that the electronic natures of allyl moiety andparasubstituents play the main role in radical scavenging activity and subsequently LOX inhibition potency of the synthetic inhibitors. Among the synthetic compounds, 2,6-diallyl-4-(hexyloxy)phenol (42) and 2,6-diallyl-4-aminophenol (47) showed the best results for LOX inhibition (IC50= 0.88 and 0.80 mu M, respectively).

Density functional theory (DFT) at the SMD/M06-2X/def2-TZVP//SMD/M06-2X/LANL2DZ(d),6-31G(d) level was used to explore the regioselective double oxidation of phenols by a hypervalent iodine(v) reagent (IBX) to give o-quinones. The oxidative dearomatization commences with the ligand exchange between IBX and phenol, yielding a phenolate complex, followed by the first redox process, which reduces iodine(v) to iodine(iii). Both the processes (the ligand exchange and the first redox reaction) were found to be mediated by a less stable isomer of iodine(v) species. We found that although the first redox process preferentially proceeds via an associative pathway, an electron withdrawing substituent on the phenol ring decreases its accessibility. The inspection of the electronic structure of the redox transition state indicates that the phenolate involved in the iodine(v) reduction has some phenoxenium character. The intrinsic stability of a phenoxenium ion is calculated to be highly sensitive to the substituent on the phenol ring. Since the electron withdrawing substituents considerably decrease the stability of the phenoxenium, they render the iodine(v) to iodine(iii) reduction energy consuming. Once the first redox step has completed, a catechol-iodine(iii) complex is formed, from which the second redox process produces the final o-quinone product via a carboxylate-assisted transition structure. This transition structure gains stability by hydrogen bond interaction between the catechol OH and carboxylate group. Such an interaction results in the phenolate not having any phenoxenium character in the transition structure, thus making the activation barrier to the second redox step independent from the substituent on the phenol ring.
