A series of pincer-type compounds possessing an N-heterocyclic carbene precursor and a carboxyl group as proton transfer agent were synthesized used organocatalysts for the cycloaddition epoxides with CO2. In this context, we have demonstrated high activity these one-component in CO2 transformation to cyclic carbonates under ambient conditions (room temperature, 1 bar CO2). The catalytic potential multifunctional on challenging internal is particularly deserving mention because that are able...
An N,N,N‐type Cu(Ⅱ) complex‐catalyzed desaturation method for converting alcohols, ketones, lactones, and lactams to their α,β‐unsaturated carbonyl compounds is reported. The dehydrogenation reaction can be conducted with a green terminal oxidant O2 without requiring strong acid/base or stoichiometric oxidants. complex/TEMPO/O2 system uses non‐noble catalyst, as well demonstrates high activity functional group tolerance. Notably, H2O the byproduct produced overoxidation not observed during...
Herein, we report that binuclear copper complexes used as dehydrogenative catalysts, combined with oxygen an oxidant and 2,2,6,6-tetramethylpiperidinyl-1-oxide (TEMPO) additive, are capable of effectively catalyzing the successive dehydrogenation aromatic propanols to produce α,β-unsaturated aldehydes. This method has advantages high efficiency, simple operation, oxidant. The reaction mechanism continuous was investigated by in situ infrared spectroscopy control experiments. process...
Herein, we report that an efficient and practical organocatalyzed strategy enables direct amidation of a wide range carboxylic acids variety amines. The system is proved to be suitable for the synthesis small molecular peptides from protected amino acids, method was successfully applied late stage functionalization drug molecules or pharmaceutical intermediates. Mechanistic studies by control experiments, in situ infrared spectroscopy, 11B nuclear magnetic resonance (11B NMR), density...
Abstract With certain amounts of sodium tert ‐butoxide and ‐butanol as additives, catalytic an inexpensive easy‐to‐handle copper source Cu(OAc) 2 ⋅ H O, a commercially available air‐stable non‐racemic dipyridylphosphine ligand, well the stoichiometric desirable hydride donor polymethylhydrosiloxane (PMHS), formed versatile in situ catalyst system for enantioselective reduction broad spectrum prochiral diaryl aryl heteroarylketones air, high yields with good to excellent enantioselectivities...
Abstract Bismuth‐containing therapies are suggested as first‐line and rescue alternatives for gastric ulcer (GU) treatment Helicobacter pylori eradication. The current strategy is called quadruple therapy includes proton pump inhibitors, bismuth, two broad‐band antibiotics. This fact may affect medication compliance, leading to a resistance rate of more than 25% clarithromycin or metronidazole. To counter this, from the perspective natural products, an intragastric‐targeting all‐in‐one...
The first example of a photocatalyst-free strategy for the photo-promoted synthesis gem -dihaloenones is developed.
A new set of reaction conditions has been established to facilitate the copper-catalyzed enantioselective 1,4-reduction β-(acylamino)acrylates toward a selection β-alkyl-β-amino acid derivatives in high yields and with uniformly ee values (up 99%) irrespective use (E)- or (Z)-substrates.
Abstract Echinococcus granulosus sensu lato has complex defence mechanisms that protect it from the anti-parasitic immune response for long periods. cyst fluid (EgCF) is involved in escape. Nevertheless, whether and how EgCF modulates inflammatory macrophages remains poorly understood. Here, real-time polymerase chain reaction enzyme-linked immunosorbent assay revealed could markedly attenuate lipopolysaccharide (LPS)-induced production of pro-inflammatory factors including tumour necrosis...
In order to prevent the slow degradation of pristine water ecosystems caused by increasing SO 4 2− in natural bodies (lakes and rivers), innovative cost-effective remediation techniques are urgently required.
Abstract We reported an efficient method for α‐alkylation of ketones with benzyl alcohols using the pyridine‐bridged pincer‐type N ‐heterocyclic carbenes nickel complexes as catalysts. A wide range and were efficiently converted into various alkylated products in moderate to high yields. In addition, these also successfully applied synthesis a quinoline derivatives.
A variety of strategies for direct alkoxylation the benzyl C–H bond have been developed toward construction ethers. The light-induced provides an alternative strategy synthesis these important intermediates. photocatalyzed has dominated by metal-catalyzed methods. Herein, we reported a light-driven organocatalytic approach use 9,10-dibromoanthracene as photocatalyst and employing N-fluorobenzenesulfonimide oxidant. This reaction proceeds at room temperature is capable converting alkyl...
Wulungu Lake is a vital fishery area in Xinjiang. However, the concentration, enrichment rules, and sources of As, Cd, Cr, Cu, Hg, Ni, Pb, Zn aquatic organisms, have rarely been investigated. The results suggest that concentrations were higher than those recommended by national standards for edible fish some species. dependent on concentration trace metals water environment (p < 0.05). body weights significantly negatively correlated with only Hg 0.05); however, their lengths positively...
Abstract A new set of reaction conditions has been established and allowed for the first non‐noble Cu(II)‐catalyzed asymmetric 1,4‐hydrosilylation N ‐aryl β ‐enamino esters under air to afford a selection ‐amino acid moderate‐to‐good enantiopurities ( ee up 91%).
Abstract Transcriptional regulator GntR controls diverse physiological functions necessary for Brucella survival. In the intracellular pathogen , has been shown to regulate expression of genes related virulence. However, precise determination direct targets so far proved elusive. Therefore, we performed chromatin immunoprecipitation GntR10 followed by next‐generation sequencing (ChIP‐seq). We selected target gene BAB1_1163 directly regulated and created mutant (2308Δ1163) from virulent...
Abstract Synthesizing benzyl skeleton derivatives via direct oxidation of functionalized benzylic C−H bonds has received extensive research attention. Herein, a method was developed to prepare carbonyl compounds photoinduced aerobic ubiquitous mediated by bromine radicals and tribromomethane radicals. This employed commercially available CBr 4 as hydrogen atom transfer reagent precursor, air an oxidant, water reaction solvent, tetrabutylammonium perchlorate (TBAPC) additive under mild...
