The new electrocatalytic multicomponent transformation has been found: the electrolysis of arylaldehydes, N,N ‘-dimethylbarbiturate, and cycloxehane-1,3-diones in alcohols in the presence of sodium bromide as a mediator in an undivided cell results in the formation of substituted unsymmetric spirobarbituric dihydrofurans in 62%-76% yields. The optimized reaction conditions and a mechanistic rationale for this electrocatalytic multicomponent transformation are presented. This new electrocatalytic process is a facile and efficient way to produce substituted unsymmetric spirobarbituric dihydrofurans containing both barbituric and 3,5,6,7-tetrahydro-1-benzofuran-4(2H)-one fragments, which are promising compounds for different biomedical applications, among them are anticonvulsants, anti-AIDS agents, and antiinflammatory remedies. The scaffold approach was employed to find a protein, which may be influenced by the synthesized compounds-human aldose reductase was proposed. It was shown by molecular docking studies that such a scaffold search is beneficial and tetrahydro-2 ‘ H,4H-spiro[benzofuran-2,5 ‘-pyrimidines] used in this approach are promising for the development of novel aldose reductase inhibitors.

Urease is a bacterial enzyme that is responsible for virulence of various pathogenic bacteria such as Staphylococcus aureus, Proteus mirabilis, Klebsiella pneumoniae, Ureaplasma urealyticum, Helicobacter pylori and Mycobacterium tuberculosis. Increased urease activity aids in survival and colonization of pathogenic bacteria causing several disorders especially gastric ulceration. Hence, urease inhibitors are used for treatment of such diseases. In search of new molecules with better urease inhibitory activity, herein we report a series of acridine derived (thio) semicarbazones (4a-4e, 6a-6l) that were found to be active against urease enzyme. Molecular docking studies were carried out to better comprehend the preferential mode of binding of these compounds against urease enzyme. Docking against urease from pathogenic bacterium S. pasteurii was also carried out with favorable results. In silico ADME evaluation was done to determine drug likeness of synthesized compounds.

Use of green chemistry and alternative strategies has been explored to prepare diverse organic derivatives. The combination between heterogeneous catalyst, environmentally benign reaction and high-yielding methods is gaining momentum. Herein, a defective 6-connected Hf-MOF, named Hf-BTC, was efficiently synthesized and characterized for the heterogeneous catalysis under microwave irradiation. The MOF features including structural defect, porosity, acidity, and stability was analyzed by powder X-ray diffraction, N-2 sorption isotherms, acid-base titration, and thermal gravimetric analysis. In the catalytic studies, the Brunsted-Lewis dual acidic HfBTC was efficiently applied for the synthesis of the heterocyclic compounds via the microwave-assisted cycloaddition and condensation reactions. The reactions proceeded smoothly in the presence of the Hf-MOF with a broad scope of substrates provided the expected products in high to excellent yields (up to 99 %) for few minutes and the catalyst could be easily recycle over many consecutive reactions without loss of its reactivity and structure.

The porous bioceramic scaffolds require favorable mechanical properties and excellent bioactivity to promote bone repair. In this work, 45S5 bioglass (R) & biphasic calcium phosphate (BCP) bioceramic scaffolds with a diamond lattice structure (porosity of 70%) were manufactured accurately by digital light processing (DLP). After optimizing the solid loading of bioceramic suspension to 40 vol%, scaffolds with the minimum pore size of 400 mu m were fabricated successfully under exposure energy of 12.54 mJ/cm(2). In the initial stage of sintering, crystallization occurred during 45S5 bioglass (R) itself, bioglass also promoted hydroxyapatite (HA) decomposition to tricalcium phosphate (TCP). With extending holding time to 4 h, Si4+ from 45S5 bioglass (R) diffused into TCP to produce Ca-5(PO4)(2)SiO4, which could enhance the compressive strength of bioceramic scaffolds. Meanwhile, bioglass would assist the growth and roughening of ceramic grains because of the ion-diffusion from bioglass to BCP. However, as holding time extended to 6 h, abnormal grain growth and cracks occurred which would decrease compressive strength. The best value of compressive strength is 1.735 MPa at the holding time of 4 h. 45S5 bioglass (R) also accelerated ion exchange such as Si4+ and CO32- between bioceramic and SBF solution. This kind of bioceramics may be used as bioactive scaffolds with customizable fine structures and provide potential applications in bone tissue engineering.

We report the use of a rhodium(II) dimer in visible light photoredox catalysis for the aerobic oxidation of arylboronic acids to phenols under mild conditions. Spectroscopic and computational studies indicate that the catalyst Rh-2(bpy)(2)(OAc)(4) (1) undergoes metal-metal to ligand charge transfer upon visible light irradiation, which is responsible for catalytic activity. Further reactivity studies demonstrate that 1 is a general photoredox catalyst for diverse oxidation reactions.

A magnetic Fe3O4 supported glutathione catalyst was synthesized in a convenient and eco-friendly manner and characterized using FT-IR, XRD, TGA, TEM, VSM, EDX, and elemental analysis. This nano-organocatalyst exhibited excellent catalytic activity in the synthesis of a wide variety of 1,4-dihydropyridine derivatives. The catalyst was easily separated from the reaction mixture through using an external magnet and was reused in six consecutive runs with only a slight decrease in its catalytic activity. Other significant advantages of this method are shorter reaction time, excellent yield, simple work-up procedure, easy catalyst handling, and the high stability of the catalyst, which renders the protocol economic and sustainable.

Utilization of lignocellulosic biomass is increasingly important. Jasminum nudiflorum Lindl. (JNL) is a widely cultivated landscape plant in China. To evaluate the chemical components, pyrolysis characteristics as well as the potential values of JNL bark for utilization, the components were extracted using methanol, ethanol, and benzene/ethanol (2:1, v/v) and pyrolyzed from room temperature to 300 ?C, respectively. Many components were detected in the extracts and the pyrolyzates of JNL bark and their chemical properties were analyzed. The compounds identified in the extracts and the pyrolyzates of JNL bark included acids, aldehydes, alcohols, esters, ketones, aromatics, saccharides, olefins, and nitrogen-containing compounds. Some of the identified compounds, such as urs-12-en-28-al, 3-(acetyloxy)-, (3.beta.)-, 5-hydroxymethylfurfural, and vanillin, are widely used in the medical, energy, and food industries. The pyrolysis of JNL bark using thermogravimetric (TG) analyzer showed the highest reaction rate occurred at between 200 and 300 ?C where the maximum mass loss was observed. According to the Coats-Redfern method, the calculated apparent activation energy (E) and pre-exponential factor (A) of the pyrolysis process of JNL bark were 52.04 kJ mol- 1 and 3.14 ? 105 min-1, respectively. This research provides information on the components and pyrolysis characteristics of JNL bark, which shows great potential for application in medical, food, and chemical industries.

A novel synthetic method for flavonol from 2′-hydroxyl acetophenone and benzaldehyde promoted by pyrrolidine under an aerobic condition in water is established. This protocol was supported by efficient synthesis of 44 common examples and three natural products. The alpha, beta-unsaturated iminium ion (enimine ion E) was proved to be the key intermediate in the reaction. (H2O)-O-18 and O-18(2) isotope tracking experiments demonstrated that both water and the aerobic atmosphere were necessary to ensure the transformation. The selectivity for flavonol or aurone was originated from solvent-triggered intermediates, which were determined by UV-visible spectra from isolated enimine. The phenol-iminium E-A is dominant in water and the ketoenamine intermediate E-B is prevalent in acetonitrile. In the presence of pyrrolidine and oxygen, E-A leads to flavonol through E-I, a zwitterionic-like phenoloxyl-iminium ion, following the key steps of cyclization and a [2 + 2] oxidation; E-B proceeds through path II, a radical process induced by photolysis of E-B with both pyrrolidine and oxygen, to afford aurone. Preliminary mechanistic studies are reported.

Development of tunable photonic devices having molecular dimensions is an active research area in nonlinear optics which continues to evolve and impact many technologies. Here, we demonstrate the tailoring of nonlinear optical properties of nitrochalcone derivatives by engineering the donor-acceptor configurations on either end of the molecules, to control the intramolecular charge transfer process. The central pi-bridge in chalcones provides delocalized electrons which lead to the nonlinear polarizability observed in these molecules. Optical nonlinearity is studied by means of second harmonic generation (SHG) and open aperture Z-scan measurements. Samples show optical limiting behaviour in the nanosecond excitation regime due to excited state absorption (ESA) and two-photon absorption (2PA) phenomena. Our study highlights the importance of structure-property correlations in molecular designs.

Prompted by the observation that the regioselectivities of phenolate reactions (C versus O attack) are opposite to the predictions by the principle of hard and soft acids and bases, we performed a comprehensive experimental and computational investigation of phenolate reactivities. Rate and equilibrium constants for the reactions of various phenolate ions with benzhydrylium ions (Aryl(2)CH(+)) and structurally related quinone methides have been determined photometrically in polar aprotic solvents. Quantum chemical calculations at the SMD(MeCN)/M06-2X/6-31+G(d,p) level confirmed that O attack is generally favored under kinetically controlled conditions, whereas C attack is favored under thermodynamically controlled conditions. Exceptions are diffusion limited reactions with strong electrophiles, which give mixtures of products arising from O and C attack, as well as reactions with metal alkoxides in nonpolar solvents, where oxygen attack is blocked by strong ion pairing. The Lewis basicity (LB) and nucleophilicity (N, s(N)) parameters of phenolates determined in this work can be used to predict whether their reactions with electrophiles are kinetically or thermodynamically controlled and whether the rates are activation-or diffusion-limited. Comparison of the measured rate constants for the reactions of phenolates with carbocations with the Gibbs energies for single electron transfer manifests that these reactions proceed via polar mechanisms.
