Nano copper ferrite catalyst is prepared and characterized by scanning electron microscopy, energy dispersive X-ray, X-ray diffraction, vibrational sample magnetometry, and Fourier transform infrared. The catalytic activity is probed for cross-dehydrogenative coupling of aromatic aldehydes in the presence of tert-butyl hydroperoxide as the oxidant. This catalytic protocol appears as a simple, rather cheap, clean, and efficient practical strategy for the synthesis of symmetrical anhydrides, with proper efficiency (66%). The catalyst can be easily separated from the reaction mixture by an external magnet and reused several times in subsequent reactions, without any measurable loss of its efficiency. [GRAPHICS] .

Essential oils (EOs) from anise seeds (Pimpinella anisum) collected in the Algerian region were extracted by microwave-assisted hydrodistillation (MAHD) and hydrodistillation (HD). The oil yield (%), chemical composition, energetic consumption and the antimicrobial properties were evaluated of the obtained EO. The yields obtained by both processes were 2.81 +/- 0.01% for 90 minutes and 3.30 +/- 0.05% for 330 minutes for MAHD and HD, respectively. The determination of the chemical composition of EOs by GC-MS revealed the presence of a majority compound,trans-anethole 81.52% and 91.31% for MAHD and HD, respectively. The other main compounds present in the oils for MAHD and HD were, respectively: methyl chavicol (estragole) (0.63%-1.39%),cis-anethole (0.23%-0.34%), anisaldehyde (1.1%-1.57%), anisyl methyl ketone (0.28%-0.13%),trans-methyl isoellgenol (0.31%-0.17%),gamma-himachalene (0.5%-0.36%),trans-pseudoisoeugenyl 2-methylbutyrate (6.53%-2.53%) and epoxy-pseudoisoeugenyl 2-methylbutyrate (2.01%-0.56%). The EO obtained by MAHD detected other compounds, fenchone 0.41%, limonene 0.68%,cis-jasmolacatone extra C 0.41%,trans-isolongifolanone 0.2% and alpha-himachalene 0.16%. The energetic consumption by MAHD was significantly less than HD. Theoretical data from mathematical modelling were compared with practical data, and the coefficient of determination was between 0.93 and 0.97. The sensibility of bacterial strains to the essential oil obtained by MAHD is marked relatively to that obtained by HD, and for the sensibility of fungal strains, it was conserved. The MAHD process revealed a good yield of anise seeds EOs while reducing extraction time and energetic consumption. The EO extracted by this process revealed the presence of other compounds while improving antibacterial activity.

Cocatalyst loading is widely used as an approach in photocatalysis to expedite photoinduced charge separation and interfacial oxidation-reduction kinetics, which are crucial factors for affecting redox catalysis efficiency over semiconductor-based photocatalysts. However, tackling the key problem of cocatalyst loading position over heterojunction photocatalysts is still a great challenge. We herein report a facile and general light-tuning photodeposition strategy to realize site-directed spatial loading of diverse cocatalysts (MoS2, NixS, NixO, NixP, Pt) onto a CdS/TiO2 heterojunction photocatalyst, thereby abating surface charge recombination and markedly improving the photoredox-catalyzed activity of hydrogen evolution and selective oxidation of alcohol. This work highlights the wide scope of manipulating light to spatially regulate the cocatalyst loading position, thereby optimizing surface/interface charge recombination dynamics and ameliorating the net efficiency of charge separation and photoredox catalysis.

Intermediates in aromatic amino acid biosynthesis can serve as substrates for the synthesis of bioactive compounds. In this study we used two intermediates in the shikimate pathway of Escherichia coli, chorismate and anthranilate, to synthesize three bioactive compounds: 4-hydroxycoumarin (4-HC), 2,4-dihydroxyquinoline (DHQ), and 4-hydroxy-1-methyl-2(1H)-quinolone (NMQ). We introduced genes for the synthesis of salicylic acid from chorismate to supply the substrate for 4-HC and the gene encoding N-methyltransferase for the synthesis of N-methylanthranilate from anthranilate. Polyketide synthases and coenzyme (Co)A ligases were tested to determine the optimal combination of genes for the synthesis of each compound. We also tested several constructs and identified the best one for increasing levels of endogenous substrates for chorismate, anthranilate, and malonyl-CoA. With the use of these strategies, 255.4 mg/L 4-HC, 753.7 mg/L DHQ, and 17.5 mg/L NMQwere synthesized. This work provides a basis for the synthesis of diverse coumarin and quinoline derivatives with potential medical applications.

A postpolymerization nucleophilic aromatic substitution reaction is used as a strategy to efficiently diversify conjugated polymers. Conjugated polymers and small molecular models bearing tetrafluorophenyl and octafluorobiphenyl units are reacted with thiophenol derivatives, phenol derivatives, and carbazole in the presence of bases. Model reactions provide insights into the reactivity, numbers and patterns of substitution, structural features, and spectroscopic data. Thiophenol derivatives and carbazole achieve complete substitution of fluorine atoms in both the polymer and the model reactions, whereas phenol derivatives result in disubstitution in each arene ring with para-selectivity. The highly twisted and structurally rigid main chain structures are confirmed for a fully substituted arene motif in both the polymers and the models, resulting in the formation of syn- and anti-atropisomer or axial chirality and in the twisted intramolecular charge transfer character. The obtained polymers and models show unique optical and electrochemical properties, including phosphorescence at low temperatures in the case of the sulfur-containing materials.

Until now, the effective photocatalytic oxidation of benzyl alcohol to benzaldehyde with high selectivity is still a great challenge. It is reported that the carrier separation rate is the key factor affecting the photocatalytic activity, and the formation of heterojunction is an effective solution to hinder electron-hole recombination. SnS with a narrow band gap has excellent light absorption performance, which covers the whole visible light region. After compounding with g-C3N4, the light utilization of the SnS/g-C3N4 photocatalyst is effectively improved. In addition, a Z-scheme heterojunction is formed between SnS and g-C3N4 due to the matched energy levels, which accelerates the separation of electrons and holes and improves the conversion of benzyl alcohol effectively. In this paper, the charge separation is accelerated to promote the reaction by the in situ construction of Z-scheme heterojunctions; the preparation method, reaction mechanism and energy level structure of the photocatalyst can play a certain guiding role in the organic conversion reaction.

Cerebral amyloid angiopathy (CAA) commonly found in the aged is pathologically characterized by beta-amyloid (A beta) deposition in the walls of arteries and capillaries of brain. In this study, four flexible multidentate benzyldiamine derivatives as potential probes for cerebrovascular A beta deposition were designed and synthesized. In in vitro inhibition assays, the ligands 18-21 displayed high affinities for A beta aggregates with K-i values of 1.45 +/- 0.53 nM, 1.68 +/- 0.35 nM, 1.16 +/- 0.23 nM and 1.72 +/- 0.19 nM, respectively. A significant improvement in the binding affinity over the monomer, compounds 9-12 or benzyldiamine derivatives, demonstrated the applicability of the multidentate approach. The underlying mechanism of these novel A beta agents was explored by molecular docking technique, which theoretically verified the high affinities of the multidentate benzyldiamine derivatives for A beta aggregates. Moreover, the molecular masses of the ligands 18-21 are more than 700 Dalton, which are believed to be hardly capable of penetrating blood brain barrier. In this regard, these ligands could be used to distinguish CAA from Alzheimer’s disease which is another A beta-related disorder disease. To convert these ligands to positron emission tomography imaging agents, we attempted to radiosynthesize [F-18]18. Though the radiolabeling was not very successful, the preliminary results suggested that these newly proposed multidentate benzyldiamine derivatives may be used as potential A beta imaging agents in cerebral amyloid angiopathy.

In this study, an efficient hybrid nanocatalyst made of guar gum (guarana, as a natural basis), magnetic iron oxide nanoparticles, and copper(I) oxide nanoparticles (Cu2O NPs) is fabricated and suitably applied for catalyzing the multicomponent (three- and four-component) synthesis reactions of imidazole derivatives. Here, an easy preparation strategy for this novel catalytic system (Cu2O/Fe3O4@guarana) is presented. Then, the application of this catalytic system for the synthesis of imidazole derivatives is precisely investigated. For this purpose, ultrasonication is introduced as an efficient and fast method. In summary, the high catalytic efficiency of Cu2O/Fe3O4@guarana nanocomposite is well demonstrated by high reaction yields obtained in the presence of a small amount of this nanocomposite, under mild conditions. Wide active surface area, substantial magnetic behavior, excellent heterogeneity, suitable stability, well reusability, and etc. have distinguished this catalytic system as an instrumental tool for facilitating the complex synthetic reactions.
