The enantioselective aminocatalytic alpha-chlorination of aldehydes is a challenging reaction because of its tendency to proceed through neutral intermediates in unselective pathways. Herein we report the rational shift to a highly selective reaction pathway involving charged intermediates using hexafluoroisopropanol as solvent. This change in mechanism has enabled us to match and improve upon the yields and enantioselectivities displayed by previous methods while using cheaper aminocatalysts and chlorinating agents, 80-95% less amount of catalyst, convenient temperatures, and shorter reaction times.

The effluent from conventional treatment process (including anaerobic digestion and anoxic-oxic treatment) for pig farm wastewater was difficult to treat due to its low ratio of biochemical oxygen demand to chemical oxygen demand (BOD5/CODCr) (<0.1). In the present study, electro-Fenton (EF) was used to improve the biodegradability of the mentioned effluent and the properties of self-prepared CeO2 doped multi-wall carbon nanotubes (MWCNTs) electrodes were also studied. An excellent H2O2 production (165 mg L-1) was recorded, after an 80-min electrolysis, when the mass ratio of MWCNTs, CeO2 and pore-forming agent (NH4HCO3) was 6:1:1. Results of scanning electron microscopy (SEM), transmission electron microscope (TEM) and x-ray photoelectron spectroscopy (XPS) showed that addition of NH4HCO3 and the doping of CeO2 could increase the superficial area of the electrode as well as the oxygen reduction reaction (ORR) electro-catalytic performance. The BOD5/CODCr of the wastewater from the first stage AO process increased from 0.08 to 0.45 and CODCr reduced 71.5% after an 80-min electrolysis, with 0.3 mM Fe2+ solution. The non-biodegradable chemical pollutants from the first stage AO process were degraded by EF. The non-biodegradable pollutants identified by LC-MS/MS in the effluent from AO process including aminopyrine, oxadixyl and 3-methyl-2-quinoxalinecarboxylic acid could be degraded by EF process, with the removal rates of 81.86%, 34.39% and 7.13% in 80 min, and oxytetracycline with the removal rate of 100% in 20 min. Therefore, electro-Fenton with the new CeO2-doped MWCNTs cathode electrode will be a promising supplement for advanced treatment of pig farm wastewater. (C) 2020 Elsevier Ltd. All rights reserved.

A convenient and eco-friendly, one-pot synthetic protocol for pharmaceutically important pyran-based heterocyclic compounds is repeated herein. The reactions were carried out at room temperature in a water-ethanol solvent mixture under direct irradiation of UV365 light source in the absence of photocatalyst. The merits of the present protocol include mild and catalyst-free reactions, green procedures, and high yields. The added advantage of this protocol is that it can be applied for large-scale synthesis of various pyran-based heterocyclic compounds without employing any expensive catalyst. Also, in vitro antibacterial screening of pyran derivative was investigated against both Gram-positive Bacillus cereus (B. cereus) and Gram-negative bacteria Escherichia coli (E. coli).

An efficient metal-free strategy for the synthesis of alpha-substituted homoallylamine derivatives has been developed via a 1,1,1,3,3,3-hexafluoro-2-propanol (HFIP)-promoted 2-aza-Cope rearrangement of aldimines, generated in situ by condensation of aldehydes with easily accessible 1,1-diphenylhomoallylamines. This reaction provides rapid access to alpha-substituted homoallylamines with excellent functional group tolerance and yields. The reaction takes place at room temperature and no chromatographic purification is required for product isolation. The synthetic utility of the current method is further demonstrated by the transformation of the obtained benzophenone ketimines into N-unprotected homoallylamines, an alpha-amino alcohol and an alpha-amino amide.

Urban wildfires may generate numerous unidentified chemicals of toxicity concern. Ash samples were collected from burned residences and from an undeveloped upwind reference site, following the Tubbs fire in Sonoma County, California. The solvent extracts of ash samples were analyzed using GC- and LC-high-resolution mass spectrometry (HRMS) and using a suite of in vitro bioassays for their bioactivity toward nuclear receptors [aryl hydrocarbon receptor (AhR), estrogen receptor (ER), and androgen receptor (AR)], their influence on the expression of genetic markers of stress and inflammation [interleukin-8 (IL-8) and cyclooxygenase-2 (COX-2)], and xenobiotic metabolism [cytochrome P4501A1 (CYP1A1)]. Genetic markers (CYP1A1, IL-8, and COX-2) and AhR activity were significantly higher with wildfire samples than in solvent controls, whereas AR and ER activities generally were unaffected or reduced. The bioassay responses of samples from residential areas were not significantly different from the samples from the reference site despite differing chemical compositions. Suspect and nontarget screening was conducted to identify the chemicals responsible for elevated bioactivity using the multiple streams of HRMS data and open-source data analysis workflows. For the bioassay endpoint with the largest available database of pure compound results (AhR), nontarget features statistically related to whole sample bioassay response using Spearman’s rank-order correlation coefficients or elastic net regression were significantly more likely (by 10 and 15 times, respectively) to be known AhR agonists than the overall population of compounds tentatively identified by nontarget analysis. The findings suggest that a combination of nontarget analysis, in vitro bioassays, and statistical analysis can identify bioactive compounds in complex mixtures.

In the current research, much attention is paid to heterogenized nanostructure. Herein, we report the green synthesis magnetic nanoparticles (MNPs) of cobalt ferrite by the immobilization of erbium (Er) coated with folic acid (FA) which show effective catalytic properties and recyclability. Full characterizations with field emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM), energy-dispersive X-ray spectroscopy (EDX), X-ray atomic mapping, thermal gravimetric analysis (TGA), X-ray diffraction (XRD), vibrating sample magnetometer (VSM), inductively coupled plasma-optical emission spectrometry (ICP-OES), and Fourier-transform infrared (FT-IR) spectroscopy techniques were undertaken to uncover structural properties of the prepared magnetic catalyst. The obtained nanohybrid complexes as efficient, recyclable, and green heterogeneous systems pave the way for producing pyrano[2,3-d]pyrimidinone and dihydropyrano[3,2-c]chromenes derivatives by the one-pot three-component condensation reaction of various aldehydes, malononitrile, and hydroxycoumarin or barbituric acid in green condition. This easily prepared organometalic catalyst presents many superiorities such as operational simplicity, high yield, short reaction time, utilization of commercially available or easily accessible starting materials, eco-friendly properties, and excellent purity. Most importantly, erbium-FA-coated CoFe2O4 can be easily separated and recycled from the reaction system using an external magnetic field. The magnetically recoverable biocatalyst can be recycled and reused six times while maintaining high activities. The activity of the magnetic catalyst can be maintained at more than 80% of that of the previous cycle. This research solves the recovery problem encountered in industrial applications of biocatalysts and presents a clean and green method for preparing pyrimidinones and chromenes.

COA of Formula: C14H10O. I found the field of Polymer Science very interesting. Saw the article Highly transparent and organosoluble poly(ether amide)s derived from new diamine: 10,10-bis [4-(4-amino-2-pyridinoxy)phenyl]-9(10H)-anthracenone published in 2020, Reprint Addresses Huang, ZZ (corresponding author), Jiangxi Normal Univ, Minist Educ, Key Lab Funct Small Organ Mol, Nanchang, Jiangxi, Peoples R China.. The CAS is 90-44-8. Through research, I have a further understanding and discovery of Anthrone.

A new aromatic diamine, 10,10-bis [4-(4-amino-2-pyridinoxy)phenyl]-9(10H)-anthracenone (BAPPA) was synthesized from anthrone as the starting material, and the corresponding pyridine- and anthrone-containing poly(ether amide)s (PEAs) were prepared from BAPPA with various aromatic diacid chlorides via a low-temperature solution polycondensation. The resulting PEAs having number-average molecular weights (M-n) of 29,500-33,400 g/mol with the polydispersity index ranged from 1.75 to 1.84, were all amorphous, and displayed excellent thermal stability with the glass transition temperatures of 263-355 degrees C, the temperatures of 415-441 degrees C at 5% weight loss and the higher than 50% residues at 800 degrees C in nitrogen. These new PEAs were soluble in polar solvents such as N-methyl-2-pyrrolidone, N,N-dimethylacetamide and pyridine, even almost in tetrahydrofuran at room temperature and could form transparent, strong and flexible films with tensile strengths of 84-97 MPa, tensile moduli of 2.1-3.2 GPa and elongations at break of 4-13%. Also, the present PEAs exhibited high optical transparence with the UV cutoff wavelength in the 342-362 nm range, and 83-90% transmittance at 500 nm. These results indicated the introduction of anthrone and pyridine groups into the backbone could improve the solubility and transparence of polyamides.
