Synthesis of substituted naphtho[1,2-b]benzofuran-7(8H)-ones via photoinduced rearrangement of 4H-chromen-4-one derivatives

A simple and efficient method was developed for the synthesis of substituted naphtho[1,2-b]benzofuran-7(8H)-ones based on the photorearrangement reaction of 4H-chromen-4-one derivatives. The studied reaction includes the photocyclization of the hexatriene system, [1,9]-H-sigmatropic rearrangement and heterocyclic ring opening. The starting terarylenes were prepared via a new three-component tandem condensation of 3-(dimethylamino)-1-(2-hydroxyaryl)prop-2-en-1-ones, arylglyoxals and cyclic 1,3-diketones.

A comprehensive evaluation on pyrolysis behavior, kinetics, and primary volatile formation pathways of rice husk for application to catalytic valorization

Catalytic fast pyrolysis is a prospective and effective route to produce value-added products from rice husk (RH). Understanding the volatile compositions and its formation pathways as well as kinetics during RH pyrolysis is crucial and fundamental to regulate the quality of the target products since catalysts interact directly with primary volatiles. In this study, two pyrolysis coupled real-time volatile monitoring techniques (TG-FTIR and PyGC/TOF-MS) were employed to conduct comprehensive experiments for RH. The results showed that RH presented three mass loss and gaseous product evolution stages in the temperature range of 200 to 330 degrees C, 330 to 390 degrees C, and 390 to 600 degrees C, respectively. After speculating the formation pathways of the 24 main volatile species, it was indicated that 2,3-dihydro-benzofuran was the major product for hemicellulose, while 2-methoxy-4-(1-propenyl)-phenol was potentially a key active intermediate and very unstable during pyrolysis of lignin constituent in RH. In addition, pyrolysis of RH could be divided into two kinetic stages at cut-off point of 25% conversion. The first kinetic stage obeyed three-dimensional (D3) diffusion model and E-a was within 140-170 kJ/mol. In the secondary kinetic stage, Ea raised gradually to about 200 kJ/mol and pyrolysis reactions followed the second-order reaction model.

Efficient synthetic methods were established for obtaining 2-fluorobenzofurans involving various substituents. Upon being treated with 1,8-diazabicyclo[5.4.0]undec-7-ene under microwave irradiation, the alpha-unsubstituted beta,beta-difluoro-o-hydroxystyrenes underwent nucleophilic 5-endo-trigcyclization to afford the corresponding 2-fluorobenzofurans in high yields.

A Novel Benzofuran Derivative Moracin N Induces Autophagy and Apoptosis Through ROS Generation in Lung Cancer

Introduction The leaves of Morus alba L is a traditional Chinese medicine widely applied in lung diseases. Moracin N (MAN), a secondary metabolite extracted form the leaves of Morus alba L, is a potent anticancer agent. But its molecular mechanism remains unveiled. Objective In this study, we aimed to examine the effect of MAN on human lung cancer and reveal the underlying molecular mechanism. Methods MTT assay was conducted to measure cell viability. Annexin V-FITC/PI staining was used to detect cell apoptosis. Confocal microscope was performed to determine the formation of autophagosomes and autolysosomes. Flow cytometry was performed to quantify cell death. Western blotting was used to determine the related-signaling pathway. Results In the present study, we demonstrated for the first time that MAN inhibitd cell proliferation and induced cell apoptosis in human non-small-cell lung carcinoma (NSCLC) cells. We found that MAN treatment dysregulated mitochondrial function and led to mitochondrial apoptosis in A549 and PC9 cells. Meanwhile, MAN enhanced autophagy flux by the increase of autophagosome formation, the fusion of autophagsomes and lysosomes and lysosomal function. Moreover, mTOR signaling pathway, a classical pathway regualting autophagy, was inhibited by MAN in a time- and dose-dependent mannner, resulting in autophagy induction. Interestingly, autophagy inhibition by CQ or Atg5 knockdown attenuated cell apoptosis by MAN, indicating that autophagy serves as cell death. Furthermore, autophagy-mediated cell death by MAN can be blocked by reactive oxygen species (ROS) scavenger NAC, indicating that ROS accumulation is the inducing factor of apoptosis and autophagy. In summary, we revealed the molecular mechanism of MAN against lung cancer through apoptosis and autophagy, suggesting that MAN might be a novel therapeutic agent for NSCLC treatment.

Visible-Light-Induced Radical Carbo-Cyclization/gem-Diborylation through Triplet Energy Transfer between a Gold Catalyst and Aryl Iodides

Geminal diboronates have attracted significant attention because of their unique structures and reactivity. However, benzofuran-, indole-, and benzothiophene-based benzylic gem-diboronates, building blocks for biologically relevant compounds, are unknown. A promising protocol using visible light and aryl iodides for constructing valuable building blocks, including benzofuran-, indole-, and benzothiophene-based benzylic gem-diboronates, via radical carbo-cyclization/gem-diborylation of alkynes with a high functional group tolerance is presented. The utility of these gem-diboronates has been demonstrated by a 10 g scale conversion, by versatile transformations, by including the synthesis of approved drug scaffolds and two approved drugs, and even by polymer synthesis. The mechanistic investigation indicates that the merging of the dinuclear gold catalyst (photoexcitation by 315-400 nm UVA light) with Na2CO3 is directly responsible for photosensitization of aryl iodides (photoexcitation by 254 nm UV light) with blue LED light (410-490 nm, lambda(max) = 465 nm) through an energy transfer (EnT) process, followed by homolytic cleavage of the C-I bond in the aryl iodide substrates.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 14400-67-0, you can contact me at any time and look forward to more communication. Computed Properties of C6H8O2.

The Role of Oxygen in the Electrochemical Reduction of Ethyl 2-(2-(Bromomethyl)phenoxy)acetate at Carbon Cathodes in Dimethylformamide

Cyclic voltammetry (CV) and controlled-potential electrolysis (CPE) were employed to examine the direct reduction of ethyl 2-(2-(bromomethyl)phenoxy)acetate at carbon cathodes in dimethylformamide (DMF) containing tetramethylammonium tetrafluoroborate (TMABF(4)) as the electrolyte. Cyclic voltammogram of the substrate exhibits a single irreversible cathodic wave with a peak potential of -1.75 V vs SCE, which is characteristic for the reduction of organic halides in aprotic solvents. Bulk electrolyses of ethyl 2-(2-(bromomethyl)phenoxy)acetate were carried out in the absence and presence of oxygen. The product distributions were obtained by gas chromatograph (GC) as well as gas chromatograph coupled to a mass spectrometer (GC-MS). Two bicyclic compounds, ethyl 2,3-dihydro-1-benzofuran-2-carboxylate and ethyl benzofuran-2-carboxylate, were found to be formed in a total yield of more than 40% in the presence of oxygen. The reaction mechanism, in which the oxygen plays a significant role, was proposed and discussed on the basis of this study. (c) 2020 The Author(s).

Potent alpha-amylase inhibitors and radical (DPPH and ABTS) scavengers based on benzofuran-2-yl(phenyl)methanone derivatives: Syntheses, in vitro, kinetics, and in silico studies

Thirty benzofuran-2-yl(phenyl)methanones 1-30 were synthesized and characterized their structures by spectroscopic techniques. Substituted phenacyl bromide and different derivatives of 2-hydroxy-benzaldehyde treated in the presence of anhydrous K2CO3 in acetonitrile at room temperature to afford the desired benzofurans 1-30. All compounds were screened for their in vitro alpha-amylase inhibitory and radical scavenging (DPPH and ABTS) activities. Results revealed that para substituted compounds were found to be more active than the others with IC50 values ranges for alpha-amylase inhibition (IC50 = 18.04-48.33 JIM), DPPH (IC50 = 16.04-32.33 JIM) and ABTS (IC50 = 16.99-33.01 JIM) radical scavenging activities. Activities results were compared with the standards acarbose (IC50 = 16.08 +/- 0.07 JIM) for alpha-amylase, ascorbic acid (IC50 = 15.08 +/- 0.03 and 15.09 +/- 0.17 JIM) for DPPH and ABTS radical scavenging activities, respectively. Kinetic studies predicted that all compounds followed non-competitive mechanism of inhibition. Molecular docking results showed good protein-ligand interactions profile against the corresponding target.
