Multifunctional succinimide-based ionic liquids (SIILs) were well-designed and synthesized, and they were used as a dual solvent-catalyst for efficient transformation of CO2 and 2-aminobenzonitriles into quinazoline-2,4(1H,3H)-diones under mild conditions. The catalytic behaviors, including the effects of anion-cation structures and reaction parameters, catalyst recyclability, and versatility were thoroughly studied. The optimum [HTMG][Suc] comprising a tetramethylguanidine cation and a succinimide anion showed excellent activity toward various substituted 2-aminobenzonitrile substrates. [HTMG][Suc] was easily recyclable with superior structural integrity. The possible pathways of CO2 and 2-aminobenzonitrile activated by [HTMG][Suc] were investigated in depth, which supported the reaction mechanism well. In comparison with reported catalysts, the protocol herein exhibited comparable catalytic performance under milder and greener conditions without any addnl. organic solvents.

Zhang, Xiaheng published the artcileCopper-mediated synthesis of drug-like bicyclopentanes, Computed Properties of 1885-29-6, the main research area is bicyclopentane preparation copper iridium catalyst propellane nucleophile radical.

Multicomponent reactions are relied on in both academic and industrial synthetic organic chem. owing to their step- and atom-economy advantages over traditional synthetic sequences1. Recently, bicyclo[1.1.1]pentane (BCP) motifs have become valuable as pharmaceutical bioisosteres of benzene rings, and in particular 1,3-disubstituted BCP moieties have become widely adopted in medicinal chem. as para-Ph ring replacements2. These structures are often generated from [1.1.1]propellane via opening of the internal C-C bond through the addition of either radicals or metal-based nucleophiles3-13. The resulting propellane-addition adducts are then transformed to the requisite polysubstituted BCP compounds via a range of synthetic sequences that traditionally involve multiple chem. steps. Although this approach was effective so far, a multicomponent reaction that enables single-step access to complex and diverse polysubstituted drug-like BCP products would be more time efficient compared to current stepwise approaches. Here the authors report a one-step three-component radical coupling of [1.1.1]propellane to afford diverse functionalized bicyclopentanes using various radical precursors and heteroatom nucleophiles via a metallaphotoredox catalysis protocol. This copper-mediated reaction operates on short timescales (five minutes to one hour) across multiple (more than ten) nucleophile classes and can accommodate a diverse array of radical precursors, including those that generate alkyl, α-acyl, trifluoromethyl and sulfonyl radicals. This method was used to rapidly prepare BCP analogs of known pharmaceuticals, one of which is substantially more metabolically stable than its com. progenitor.

Ogunsipe, Abimbola published the artcileSynthesis, characterization and photostability studies on aluminium phthalocyanine chloride, Safety of Phthalonitrile, the main research area is aluminum phthalocyanine chloride microwave radiation photostability.

The synthesis, characterization and photostability studies of aluminum phthalocyanine chloride are hereby presented. Aluminum phthalocyanine chloride was synthesized by a solvent-free procedure involving microwave irradiation of a mixture of hydrated zinc chloride and 1,2-dicyanobenzene (phthalonitrile); the product was thoroughly purified and dried. The percentage yield was 83.4%. The characterization of the blue product was done via Fourier Transform IR Spectroscopy (FTIR) and UV-Visible spectrophotometry, and the results were satisfactory. In the FTIR spectrum, the formation of zinc phthalocyanine was confirmed by the band due to CN vibrations (around 2100 cm-1) which was present in the phthalonitrile (starting material), but absent in the product (aluminum phthalocyanine chloride). The UV-Visible absorption spectrum showed an intense signal at 672 nm and a weaker one around 350 nm. These bands are taken to be due to π→π* transitions within the phthalocyanine mol. The Beer-Lambert’s plot for the product resulted in a molar extinction coefficient value of 202,118 M-1 cm-1. Photodegradation studies showed that zinc phthalocyanine is very stable towards photoirradiation, with a rather small photodegradation value of 2.73 x 10-8.

Zhang, Cuicui published the artcileBaicalein triazole prevents respiratory tract infection by RSV through suppression of oxidative damage, Recommanded Product: 2-Aminobenzonitrile(Flakes or Chunks), the main research area is Secutellaria baicalein triazole respiratory syncytial virus infection antiviral; Anti-inflammatory; Bronchiolitis; Pneumonia; Tumor necrosis.

Baicalein, an isolate of secutellaria baicalensis is known for its anti-inflammatory activity. In the present study, 12-triazole derivatives of baicalein I (R = 2-OH, 4-Me, 2-Br, etc.) were synthesized and evaluated against RSV infected BEAS-2B cells in vitro and in mice model in vivo. The preventive effect of most active compound I (R = 2-CF3) against RSV infection was studied in detail. The compound I (R = 2-CF3) treatment increased IFN-β1 expression in BEAS-2B cells infected with RSV. In BEAS-2B cells treatment with compound I (R = 2-CF3) inhibited RSV-induced secretion of interleukin-6 and -8 cytokines. It decreased RSV-induced nitric oxide & malondialdehyde production and inhibited the RSV-mediated activation of NF-κB, COX-2, Stat3 and MAPK. RT-qPCR showed that compound I (R = 2-CF3) treatment of the RSV-infected mice significantly (P < 0.05) decreased viral load through reduction in the viral replication. In the mice model of RSV-infection compound I (R = 2-CF3) treatment decreased interleukin-6, -8 and tumor necrosis factor-a expression. In summary, compound I (R = 2-CF3) inhibits RSV-infection and prevents pulmonary airway inflammation through the activation of IFN signalling pathway.

Wu, Yi published the artcileLigand regulation to prepare an Fe, N, S tri-codoped hollow carbon electrocatalyst for enhanced ORR performance and Zn-air batteries, Synthetic Route of 91-15-6, the main research area is iron nitrogen sulfur carbon electrocatalyst ORR zinc air battery.

It is significant to explore high-efficiency, low-cost, and stable electrocatalysts for the oxygen reduction reaction (ORR) to substitute the precious metal platinum in electrochem. energy conversion devices. Materials with an Fe-Nx center are considered as promising catalysts to achieve this. Herein, a feasible SiO2-ZnCl2 template strategy is used to obtain nitrogen-sulfur-Fe co-doped periodic porous hollow carbon by calcining the Fe-based complexes with different ligands (1,10-phenanthroline, 2,2-bipyridine, and 1,2-dicyanobenzene). Owing to the introduction of the SBA-15 template and pore-forming agent ZnCl2, the as-prepared materials possess a large sp. surface area (SSA) and a well-defined hollow structure. Most importantly, different ligands have a crucial effect on the nitrogen content of the obtained materials, which in turn directly affects the metal active sites of ORR. The appropriate selection of 1,10-phenanthroline as the ligand creates abundant Fe-Nx active sites after the pyrolysis process. Therefore, the optimal hollow carbon (denoted as Z-CNS-Fe) derived from the complex of Fe2+ and 1,10-phenanthroline exhibits better ORR performance with a half-wave potential of 0.880 V, which is 30 mV higher than that of com. Pt/C (0.850 V). Beyond this, Z-CNS-Fe shows long-term stability and superior tolerance to methanol crossover. In addition, when Z-CNS-Fe was applied as the cathode of a primary Zn-air battery, the obtained metal-air cell provided a power d. as high as 141 mW cm-2, which exceeded that of com. Pt/C (114 mW cm-2). The high open-circuit voltage and satisfactory durability also indicate its potential practical applicability.
