Dual Rh(II)/Pd(0) Relay Catalysis for One-Pot Synthesis of alpha-Quaternary Allylated Indolin-2-ones and Benzofuran-2-ones

Cooperative Rh(II) and Pd(0) dual relay catalysis has been developed, which allowed one-pot synthesis of alpha-quaternary allylated indolin-2-ones and benzofuran-2-ones. The catalytic reaction proceeded through the sequential Rh(II)-catalyzed intramolecular aromatic C(sp(2))-H bond functionalization of alpha-diazo carbonyl compounds, followed by Pd(0)-catalyzed allylic alkylation with allylic carbonates to afford the products in high yields (up to 97%).

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 6296-53-3. Recommanded Product: N-(1,3-Dioxo-1,3-dihydroisobenzofuran-4-yl)acetamide.

Discrimination of Naturally-Occurring 2-Arylbenzofurans as Cyclooxygenase-2 Inhibitors: Insights into the Binding Mode and Enzymatic Inhibitory Activity

2-arylbenzofuran-containing compounds are chemical entities that can be naturally produced by several organisms. A wide-range of activities is described for several compounds of this kind and they are, therefore, valuable moieties for a lead finding from nature. Although there are in-vitro data about the activity of 2-arylbenzofuran-related compounds against cyclooxygenase (COX) enzymes, the molecular level of these COX-inhibiting constituents had not been deeply explored. Thus, 58 2-arylbenzofurans were initially screened through molecular docking within the active site of nine COX-2 crystal structures. The resulting docking scores were statistically analyzed and good reproducibility and convergence were found to discriminate the best-docked compounds. Discriminated compounds exhibited the best performance in molecular dynamics simulations as well as the most-favorable binding energies and the lowest in-vitro IC50 values for COX-2 inhibition. A three-dimensional quantitative activity-structure relationship (3D-QSAR) was also demonstrated, which showed some crucial structural requirements for enhanced enzyme inhibition. Therefore, four hits are proposed as lead structures for the development of COX-2 inhibitors based on 2-arylbenzofurans in further studies.

Iodocyclization in Aqueous Media and Supramolecular Reaction Control Using Water-Soluble Hosts

Iodocyclization of 2-alkynylanisoles is an efficient route for synthesizing substituted benzofurans. Reaction efficiency with copper(II) sulfate and sodium iodide in an aqueous slurry under mild conditions is a manifold higher than in organic solvents. Water-soluble hosts of the cyclodextrin family solubilize the compounds in aqueous media and affect the reaction efficiency through conformation control and steric interactions. Computational chemistry and spectral titration provide information on the host-guest complex structure and insight into the mechanistic basis of the observed effects.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 4412-91-3 is helpful to your research. Category: benzofurans.

A [4+3] annulation of benzofuran-derived azadienes and alpha-bromohydroxamates for the synthesis of benzofuran-fused 1,4-diazepinones

A Cs2CO3-mediated formal [4+3] cycloaddition involving benzofuran-derived azadienes (BDAs) and alpha-bromohydroxamates to afford benzofuran-fused 1,4-diazepinones is established. This is the first example of using BDAs for the construction of seven-membered dinitrogen-fused heterocycles.

Experimental Study on the Surface Properties of Nanoalumina-Filled Epoxy Resin Nanocomposites

This article presents an experimental study on the surface properties of epoxy resin nanocomposites (EPNCs) manufactured with a thermosetting epoxy resin (EP)-bisphenol A diglycidyl ether (BADGE)-2-[[4-[2-[4-(Oxiran-2-ylmethoxy)phenyl]propan-2-yl]phenoxy]methyl]oxirane) and filled with alumina nanoparticles (NPs). The NPs consist of pretreated (with a silane agent) alpha alumina with irregular shapes and a 100 nm maximum size. Three weight fractions of NPs were studied: 1, 3, and 5 wt. (%). Two different epoxy (EP) resins were manufactured, one cured and postcured with bis (4-aminophenyl) methane (DDM); and another one cured with 3-dodec-2-enyloxolane-2,5-dione (DDSA) + 8-methyl-3a,4,7,7a-tetrahydro-4,7-methano-2-benzofuran-1,3-dione (MNA). The wettability and the surface roughness of the obtained EPNCs were studied through the measurement of contact angles and topographic images obtained with atomic force microscopy (AFM), respectively. Significant influence of both the loading of NPs and used curing agents was observed. EPNCs cured with DDM were shown to be hydrophobic for 0, 1, and 3 wt. (%) and hydrophilic for 5 wt. (%). Maximum surface roughness was observed for 5 wt. (%). EPNCs cured with DDSA+MNA were shown to be hydrophilic for 0 and 1 wt. (%) and hydrophobic for 3 and 5 wt. (%). The surface roughness decreased as the weight fraction of NPs increased until 3 wt. (%), and then increased for 5 wt. (%).

Synthesis and bioactivity of novel C2-glycosyl benzofuranylthiazoles derivatives as acetylcholinesterase inhibitors

A new series of C2-glycosyl benzofuranylthiazole derivatives was synthesised by the further cyclization of glycosyl thiourea and 2-(bromoacetyl)-benzofuran via Hantzsch’s method. The corresponding 2-(bromoacetyl)-benzofuran derivatives were obtained by the reaction from various salicylaldehydes, and the glycosyl thiourea was prepared through a series of steps from D-Glucosamine. The acetylcholinesterase-inhibitory activities of the products were tested by Ellman’s method. The most active compounds were subsequently evaluated for the 50% inhibitory concentration values. N-(1,3,4,6-tetra-O-benzyl-2-deoxy-beta-D-glucopyranosyl)-4-(5-methoxy-benzofuran-2-yl)-1,3-thiazole-2-amine possessed the best acetylcholinesterase-inhibition activity with a 50% inhibitory concentration of 2.03 +/- 0.26 mu M.

Bio- and chemo- transformations of glabranin and 7-O-methylglabranin and cytotoxic evaluations of the transformed products

The biotransformation of glabranin (1) with Aspergillus niger and Cunninghamella blakesleeana favoured the formation of benzofuran derivatives (3 and 4), while in contrast, its acid-catalysed chemical transformation favoured the formation of benzopyran derivatives (6 and 7). Compound 6 was further biooxidised at C-4 ‘. Biotransformation of 7-O-methylglabranin (2) proceeded via oxidation of the prenyl group and C-4’ by the same fungi, and the obtention of 11 mimics the biosynthesis of this last compound. Some compounds displayed moderate antiproliferative activity against selected human cancer cell lines, with glabranin being the most active, suggesting that the prenyl group and the phenol at C-7 are important structural determinants for cytotoxicity.

Synthesis, electrochemical, photophysical, and photovoltaic properties of new fluorescent compounds: 3H-benzofuro[2,3-b]pyrazolo[4,3-f]quinoline

The concern with fluorescent heterocyclic compounds has been growing because they can be utilized in dye-sensitized solar cells (DSSCs) as organic photosensitizers. As a result of the experiment we conducted, the following outcomes emerged: new fluorescent heterocyclic systems 3H-benzofuro[2,3-b]pyrazolo[4,3-f]quinolines ensued from reaction of 1-alkyl-5-nitro-1H-indazole with 2-(benzofuran-3-yl)acetonitrile in KOH/MeOH. New heterocyclic compounds were characterized through a use of elemental analysis and spectroscopic data. The results of the optical properties of the fluorescent compounds demonstrated that their fluorescence quantum yields are comparable to the quantum yields of such well-known fluorescent dyes as fluorescein. Furthermore, the cyclic voltammetry revealed the electrochemical attributes of the fluorescent heterocyclic systems and that reversible oxidation waves are observable in their case. In order for their photovoltaic performance parameters to be determined, the I-V curves and the IPCE spectra of the new compounds were launched into an investigation. What followed exposed that the photovoltaic performances of the foregoing compounds were 5.01% to 5.17%.
