Selective Quadruple C(sp(3))-F Functionalization of Polyfluoroalkyl Ketones

The significance of organofluorine compounds has inspired the establishment of numerousmethods for the functionalization of rather inert C-F bonds. Despite advances achieved in the manipulation of C(sp(2))-F bonds by employing transitionmetal catalysts, such as Pd, Rh, Cu, Ni, Ru, and Ir, strategies that address the paucity of effective pathways for selective activation of multiple C(sp(3))-F bonds remained challenging. In this context, we present an unprecedented coupling-aromatization-cyclization reaction of polyfluorinated ketones with diverse Nand S-nucleophiles that forms regiodefined perfluoroalkylated naphtho[1,2-b] furan/benzofuran derivatives by harnessing Co-promoted distinctive quadruple C(sp(3))-F bonds cleavage relay. This chemistry involving controlled and successive selective defluorination at heteronuclear centers would greatly contribute to the preparation of drug-like heterocycles as well as the late-stage elaboration of bio-relevant compounds. Controlled experiments and DFT theoretical studies revealed that the combination of cheap cobalt salt with Cs2CO3 enable expeditious C-F functionalization.

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 97148-39-5. Product Details of 97148-39-5.

Application of Electrochemical Processes to Classical Iodocyclisation: Utility for Selectivity and Mechanistic Insight

The hazards and difficulties of handling elemental halogens such as I-2 can be circumvented through the electrochemical generation of these species in situ and ‘on-demand’. Advantages of this approach include the halogen being introduced into the reaction mixture at a steady rate, ensuring low concentrations to prevent halogenation of reactive aromatic rings. We also demonstrate that the Lewis acid required to promote this reaction, a Zn(II) salt, can also be generated in situ from a zinc-coated graphite electrode in a clean and energy-efficient manner. Mechanistic studies indicate an unusual pathway, which provides selectivity for the iodocyclisation without the often-problematic electrophilic aromatic iodination of the aryl ring.

New negative dielectric anisotropy liquid crystals based on benzofuran core

In this paper, new liquid crystal compounds with negative dielectric anisotropy were synthesised by regulating the substituents on the benzofuran ring. Their structures were confirmed by(1)H-nuclear magnetic resonance,(CNMR)-C-13 and mass spectra. The effects of substituent on the properties of liquid crystals were investigated. Compared with the reference compounds, the compounds with 5-ethoxy-6,7-difluorobenzofuran ring exhibit higher clearing points as well as the tendency of expansion of SmA phase range. The density functional theory calculation results reveal that the 6-ethoxy-7-fluorobenzofuran-based compound has smaller aspect ratio than that of the 5-ethoxy-6,7-difluorobenzofuran-based compound, which results in the diminish of the mesophase. Although the dielectric anisotropy of the 5-ethoxy-6,7-difluorobenzofuran-based compound is slightly lower than that of the reference compound, it has both the largest perpendicular and parallel dielectric constant.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 6296-53-3, you can contact me at any time and look forward to more communication. Formula: C10H7NO4.

Synthesis and biological evaluation of 1-(benzofuran-3-yl)-4-(3,4,5-trimethoxyphenyl)-1H-1,2,3-triazole derivatives as tubulin polymerization inhibitors

The key functions of microtubules and the mitotic spindle in cell division make them attractive targets for cancer therapy. In this study, a series of 1-(benzofuran-3-yl)-4-(3,4,5-trimethoxyphenyl)-1H-1,2,3-triazole derivatives was synthesized, and their antiproliferative activities against HCT116, HeLa, HepG2, and A549 cells were evaluated. 6-Methoxy-N-phenyl-3-(4-(3,4,5 trimethoxyphenyl)-1H-1,2,3-triazol-1-yebenzofuran-2-carboxamide (17g) exhibited the strongest antiproliferative activities, with IC50 values ranging from 0.57 to 5.7 mu M. Mechanistic studies showed that 17g inhibited tubulin polymerization, leading to the disruption of mitotic spindle formation, cell cycle arrest in the G2/M phase, and apoptosis of A549 cells. A docking study indicated that 17g was a good molecular fit at the colchicine binding site of tubulin. These results showed that 17g is a potential anticancer compound that is worthy of further development as a tubulin polymerization inhibitor.

Synthesis and Evaluation of Some Novel Essential Amino Acid-Benzofuran-Acetamide/Propanamide/Butanamide Hybrids as Potential Anticonvulsant Agents

In this study, some new essential amino acid-benzofuran-acetamide/propanamide/butanamide hybrid derivatives were synthesized. The structures of the synthesized compounds were confirmed on the basis of their elemental and spectral analyses. Their anti-seizure activity was investigated using maximal electroshock seizure (MES) and subcutaneous metrazol (scMET) seizure tests in mice. Neurotoxicity (NT) of the synthesized compounds was also determined by the rotarod test. Derivatives exhibited favorable protection in both MES and scMET tests with high safety levels in NT test. The derivatives have proven significant activity in mice and could be suggested as potential anticonvulsant lead compounds. All leucine-chlorobenzoyl benzofuran-acetamide/propanamide/butanamide hybrid derivatives (6b, 7b, and 8b) showed significant anticonvulsant activity in MES model. Compound 8b also demonstrated potent anticonvulsant activity against scMET test. The compound 8b showed maximum activity and would be considered as a lead for further optimization as anticonvulsant agent. [GRAPHICS]

Synthesis, characterization and spectroscopic investigation of N-(2-acetylbenzofuran-3-yl)acrylamide monomer: Molecular structure, HOMO-LUMO study, TD-DFT and MEP analysis

In this study, a novel acrylamide monomer was synthesized and characterized by UV-Vis, FT-IR and H-1 NMR measurements. The acrylamide monomer namely, N-(2-acetyl-benzofuran-3-yl)acrylamide (NABA), was prepared in two steps. In the first step, 1-(3-aminobenzofuran-2-yl)ethan-1 -one was synthesized by the reaction of 1-chloroacetone with 2-hydroxy-benzonitrile under basic conditions. In the second step, the obtained 1-(3-aminobenzofuran-2-yl)ethan-1 -one was reacted with acryloyl chloride and triethylamine at 0-5 degrees C temperature for obtaining NABA monomer. Then, the structural, vibrational, nuclear magnetic resonance and electronic properties for the synthesized monomer were determined by quantum chemical calculations of DFT method. The results were compared with experimental FT-IR, H-1 NMR and UV-Vis spectral data. The band gap of HOMO and LUMO show that the NABA monomer is chemically active and has charge transfer within the monomer. Moreover, molecular electrostatic potential (MEP) maps were drawn to identify reactive regions of NABA monomer. (C) 2019 Elsevier B.V. All rights reserved.

From Alkynes to Heterocycles through Metal-Promoted Silylformylation and Silylcarbocyclization Reactions

Oxygen and nitrogen heterocyclic systems are present in a large number of natural and synthetic compounds. In particular, oxa- and aza-silacyclane, tetrahydrofuran, benzofuran, cycloheptadifuranone, cycloheptadipyrrolone, pyrrolidine, lactone, lactam, phthalan, isochromanone, tetrahydroisoquinolinone, benzoindolizidinone, indoline and indolizidine scaffolds are present in many classes of biologically active molecules. Most of these contain a C=O moiety which can be easily introduced using carbonylative reaction conditions. In this field, intramolecular silylformylation and silylcarbocyclization reactions may afford heterocyclic compounds containing a carbonyl functional group together with a vinylsilane moiety which can be further transformed. Considering these two aspects, in this review a detailed analysis of the literature data regarding the application of silylformylation and silylcarbocyclization reactions to the synthesis of several heterocyclic derivatives is reported.
