Zinc oxide-decorated superparamagnetic silica attached to graphene oxide (Fe3O4/SiO2/PTS-GO-ZnO), as a novel nanocomposite, was designed, and its core-shell structure was appropriately characterized by different spectroscopy or microscopy methods and thermal techniques as well as measuring of its porosity and magnetic properties. The catalytic activity of Fe3O4/SiO2/PTSGO-ZnO, as a reusable heterogeneous catalyst, was investigated for efficient one-pot multi-component synthesis of medicinally important functionalized 2-amino-6-(2-oxo-2H-chromen-3-yl)-4-arylnicotinonitrile derivatives. The significant features of the present procedure are mild reaction conditions, low loading of the catalyst, high to quantitative yields of the desired products, avoiding the use of toxic heavy metals or solvents, simple isolation and purification of the products, and stability as well as reusability of the catalyst after at least six consecutive runs.

A novel spiro-pyrrolidine (SPD)-derived bifunctional thiourea catalyst has been developed, enabling the development of a stereoselective conjugate addition of furfurals to beta,gamma-unsaturated alpha-ketoesters. The reaction represents an example of asymmetric trienamine catalysis in the benzylic C-H functionalization of 5-benzylfurfurals, and the rigid spirocyclic framework of the catalyst is proven to be essential for a highly enantioselective transformation.

There is growing evidence that the very presence of human beings in an enclosed environment can impact air quality by affecting the concentrations of certain airborne volatile organic compounds (VOC). This influence increases considerably when humans perform different activities, such as using toiletries, or simply eating and drinking. To understand the influence of these parameters on the concentrations of selected airborne constituents, a study was performed under simulated residential conditions in an environmentally-controlled exposure room. The human subjects either simply remained for a certain time in the exposure room, or performed pre-defined activities in the room (drinking wine, doing sport, using toiletries, and preparation of a meal containing melted cheese). The impact of each activity was assessed separately using our analytical platform and exposure room under controlled environmental conditions. The results showed that prolonged human presence leads to increased levels of isoprene, TVOCs, formaldehyde and, to a lesser extent, acetaldehyde. These outcomes were further supported by results of meta-analyses of data acquired during several internal studies performed over two years. Furthermore, it was seen that the indoor concentrations of several of the selected constituents rose when the recreational and daily living activities were performed. Indeed, an increase in acetaldehyde was observed for all tested conditions, and these higher indoor levels were especially notable during wine-drinking as well as cheese meal preparation. Formaldehyde increased during the sessions involving sport, using toiletries, and cheese meal preparation. Like acetaldehyde, acrolein, crotonaldehyde and particulate matter levels rose significantly during the cheese meal preparation session. In conclusion, prolonged human residence indoors and some recreational and daily living activities caused substantial emissions of several airborne pollutants under ventilation typical for residential environments.

Prostaglandins are among the most important natural isolates owing to their broad range of bioactivities and unique structures. However, current methods for the synthesis of prostaglandins suffer from low yields and lengthy steps. Here, we report a practicability-oriented synthetic strategy for the enantioselective and divergent synthesis of prostaglandins. In this approach, the multiply substituted five-membered rings in prostaglandins were constructed via the key enyne cycloisomerization with excellent selectivity (>20:1 d.r., 98% e.e.). The crucial chiral centre on the scaffold of the prostaglandins was installed using the asymmetric hydrogenation method (up to 98% yield and 98% e.e.). From our versatile common intermediates, a series of prostaglandins and related drugs could be produced in two steps, and fluprostenol could be prepared on a 20-gram scale.

Product Details of 120-14-9. I found the field of Chemistry very interesting. Saw the article Triethylammonium Hydrogen Sulfate [Et3NH][HSO4]-Catalyzed Rapid and Efficient Multicomponent Synthesis of Pyrido[2,3-d]pyrimidine and Pyrazolo[3,4-b]pyridine Hybrids published in 2021.0, Reprint Addresses Gill, C (corresponding author), Dr Babasaheb Ambedkar Marathwada Univ, Dept Chem, Aurangabad 431004, Maharashtra, India..

An operationally simple, one-pot multicomponent reaction has been developed for the assembly of pyrido[2,3-d]pyrimidine and pyrazolo[3,4-b]pyridine derivatives (4a-4am) in excellent yields (92-94%) with high purity. The reactions were easy to perform simply by mixing of electron-rich amino heterocycles (including aminouracils and aminopyrazoles), aldehyde, and acyl acetonitrile in the presence of [Et3NH][HSO4] under solvent-free conditions. The remarkable feature of the present approach is that the ionic liquid possesses dual solvent-catalytic engineering capability. Results of this study revealed that 1 mmol of the ionic liquid catalyst under solvent-free conditions at 60 degrees C is the best reaction parameter for the construction of fused pyridine and pyrimidine derivatives in excellent yields. The present methodology showed good results under gram-scale conditions, thereby indicating its applicability in industrial as well as academic settings in the near future.

Six rhenium(I) kappa N-3-dicarbonyl complexes with 4′-(4-substituted phenyl)terpyridine ligands were evaluated in their ground and excited states. These complexes, bearing substituents of different electron-donating strengths-from CN to NMe2- were studied by a combination of transient IR (TRIR), electrochemistry, and IR spectroelectrochemistry, as well as time-dependent density functional theory (TD-DFT). They exhibit panchromatic absorption and can act as stronger photoreductants than their tricarbonyl counterparts. The ground- and excited-state potentials, absorption maxima, and lifetimes (250-750 ps) of these complexes correlate well with the Hammett sigma(p) substituent constants, showing the systematic effect of remote substitution in the ligand framework. TRIR spectroscopy allowed us to assign the lowest singlet and triplet excited states to a metal-to-ligand charge-transfer (MLCT) character. This result contrasts our previous report on analogous kappa N-2-tricarbonyl complexes, where remote substitution switched the character from MLCT to intraligand charge transfer. With the help of TD-DFT calculations, we dissect the geometric and electronic effects of coordination of the third pyridine, local symmetries, and increasing conjugation length. These results give valuable insights for the design of complexes with long-lived triplet excited states and enhanced absorption throughout the visible spectrum, while showcasing the boundaries of the excited-state switching strategy via remote substitution.

In this study, poplar wood chips were gasified in sub-and supercritical water as biomass feedstock. Hydrothermal gasification experiments were performed to examine how the reaction temperature and different type of catalysts influence conversion efficiency. The effectiveness of commercially available [alkali catalyst; KOH], naturally available [mineral catalysts; Trona [Na-3(CO3)(HCO3)center dot 2H(2)O], Dolomite [CaMg(CO3)(2)] and Borax [Na2B4O7 center dot 10H(2)O] and laboratory-prepared catalysts [metal-impregnated activated carbons; (Ni/AC) and (Ru/AC)] have been demonstrated so as to shift the product distribution toward more desirable compounds. Gaseous compound yield was increased from 29.7% to 79.3% with respect to increasing temperature while liquid compound yield decreased from 27.6% to 1.1% and solid residue from 38.0% to 15.6%. The highest H-2 (20.1 mol/kg C in poplar) and CH4 (12.7 mol/kg C in poplar) yields were obtained with Ru/AC catalyst. Carboxylic acids and 5-methyl furfural were determined as the main liquid compounds. (C) 2019 Elsevier B.V. All rights reserved.

In the current study, a new series of pyrazole derivatives4a-d,5a-dand6a-dpossessing 1,5,10,10a-tetrahydrobenzo[g]quinoline-3-carbonitrile moiety were synthesized by treating chalcones (3a-d) with hydrazine monohydrate/acetic anhydride, hydrazine monohydrate/formic acid and 4-chlorophenylhydrazine in ethanol, respectively. These reactions proceeded smoothly with satisfactory yields, and the obtained compounds were characterized using FTIR,H-1-NMR,C-13-NMR and elemental analyses. All the synthesized compounds were subjected to antibacterial activity againstBacillus subtilis,Staphylococcus aureus,Escherichia coli, andPseudomonas aeruginosabacteria and molecular docking studies. The antibacterial studies showed that all compounds exhibited good to excellent antibacterial activity against the tested bacterial strains. The structure-activity relationship studies revealed that the compounds3b,4b,5band6bbearing a chlorine atom at the para position of the phenyl group attached to pyrazole moiety in displayed the highest antibacterial activity against all the tested bacteria exceeding the standard drug ampicillin. Moreover, the molecular docking results showed that the highest scores docking have been obtained from the most active antibacterial compounds3b,3d,4b,4d,4c,5band6bwith good energy binding score within the active site of topoisomerase II DNA gyrase enzymes (PDB ID: 2XCS), suggesting that they can act by the inhibition of DNA replication. These compounds are auspicious candidates as antibacterial agents that would deserve further investigations.
