Dearomatization of 3-cyanoindoles by (3+2) cycloaddition: from batch to flow chemistry

1,3-Dipolar dearomatizing cycloadditions between a non-stabilized azomethine ylide and 3-cyanoindoles or benzofuran afford the corresponding 3D-heterocycles bearing a quaternary carbon centre at the ring junction. While 6 equivalents of ylide precursor 1 are required for full conversion in a classical flask, working under flow conditions limits the excess (3 equiv., t (R) = 1 min) and leads to a cleaner process, affording cycloadducts that are easier to isolate.

FeCl3-Mediated Friedel-Crafts Alkylation and Oxidative Annulations: Facile Synthesis of Benzofurans

An efficient method for the facile synthesis of benzofurans through FeCl3-mediated intermolecular tandem reaction of anisole with glyoxal monohydrates was reported. This process provided the privileged structures of benzofurans in moderate to good yields under mild conditions. This reaction has many advantages, such as readily available starting materials, high atom economy and good functional group tolerance. This is firstly reported that FeCl3, acting as both a Lewis acid and an oxidant, was used for the synthesis of benzofuran.

In vitro toxicokinetics and analytical toxicology of three novel NBOMe derivatives: phase I and II metabolism, plasma protein binding, and detectability in standard urine screening approaches studied by means of hyphenated mass spectrometry

Purpose Toxicokinetic studies are essential in clinical and forensic toxicology to understand drug-drug interactions, influence of individual polymorphisms, and elimination routes, as well as to evaluate targets for toxicological screening procedures. N-(2-Methoxybenzyl)-substituted phenethylamines (NBOMe analogues) intake has been associated with severe adverse reactions including deaths. 1-(1-Benzofuran-5-yl)-N-[(2-methoxyphenyl)methyl]propan-2-amine (5-APB-NBOMe), 2-(8-bromo-2,3,6,7-tetrahydrobenzo[1,2-b:4,5-b ‘]difuran-4-yl)-N-[(5-chloro-2-ethoxyphenyl)methyl]ethan-1-amine (2C-B-FLY-NB2EtO5Cl), and 2-(8-bromo-2,3,6,7-tetrahydrobenzo[1,2-b:4,5-b ‘]difuran-4-yl)-N-[(2-methoxyphenyl)methyl]ethan-1-amine (2C-B-FLY-NBOMe) are three emerging NBOMe analogues, which have encountered on the drugs of abuse market. So far, their toxicokinetic data are completely unexplored. Methods The study included mass spectrometry-based identification of phase I and II metabolites following exposure to the terminally differentiated human hepatocellular carcinoma cells (HepaRG). The determination of enzymes involved in the major phase I/II metabolic steps and determination of plasma protein binding (PPB) were done. Finally, the evaluation of the toxicological detectability by different hyphenated mass spectrometry techniques in standard urine screening approaches (SUSAs) was investigated. Results The compounds were extensively metabolized in HepaRG cells mainly via O-dealkylation, hydroxylation, glucuronidation, and combinations thereof. CYP1A2, 2D6, 2C8, 2C19, and 3A4, were involved in the initial reactions of all investigated compounds. Glucuronidation of the phase I metabolites-when observed-was mainly catalyzed by UGT1A9. The PPB of all compounds was determined to be > 85%. Only the high-resolution mass spectrometry-based SUSA allowed detection of all compounds in rat urine, but only via metabolites. Conclusions The toxicokinetic data provided by this study will help forensic and clinical toxicologists to reliably identify these substances in case of abuse and/or intoxication and will allow them a thorough risk assessment.

Reductive 3-Silylation of Benzofuran Derivatives via Coupling Reaction with Chlorotrialkylsilane

Reductive silylation of benzofurans with an electron-withdrawing group by a magnesium metal and the subsequent oxidative rearomatization by DDQ gave the selective formation of less reported 3-silylated benzofurans in moderate to good yields under mild reaction conditions with wide substituent scope. The silyl group introduced on the five-membered ring by the reductive coupling could survive with no elimination throughout the oxidation process. The silylated heteroaromatic skeleton is useful as an intermediate in organic synthesis, and its practical utility was also demonstrated by several transformation reactions.

A New Meroterpene, A New Benzofuran Derivative and Other Constituents from Cultures of the Marine Sponge-Associated Fungus Acremonium persicinum KUFA 1007 and Their Anticholinesterase Activities

Previously unreported meroterpene, acremine S (1), and benzopyran derivative, acremine T (2), were isolated, together with lumichrome (3), ergosterol (4) and ergosterol 5,8-endoperoxide, from cultures of the marine sponge-associated fungus Acremonium persicinum KUF1007. The structure of the previously unreported compounds was established based on an extensive analysis of 1D and 2D NMR spectra as well as HRMS data. The absolute configurations of the stereogenic centers of 1 were established, unambiguously, based on NOESY correlations and comparison of calculated and experimental electronic circular dichroism (ECD) spectra. Compounds 1-3 were tested for their in vitro acetylcholinesterase and butyrylcholinesterase inhibitory activities.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 591-11-7, in my other articles.

A combined experimental and DFT computations study of novel (E)-3-(benzofuran-2-yl)-2-(thiophen-2-yl)acrylonitrile(TACNBNF): Insight into the synthesis, single crystal XRD, NMR, vibrational spectral analysis, in vitro antioxidant and in silico molecular docking investigation with human peroxiredoxin 5 protein

The synthesized (E)-3-(benzofuran-2-yl)-2-(thiophen-2-yl)acrylonitrile (TACNBNF) crystal compound was characterized using FT-IR, H-1 and C-13 NMR analyses, ESI-mass and photoluminescence studies. Single crystal X-ray diffraction investigations reveal that the molecule is associated with the C (7)-H (7)center dot center dot center dot S (1) donor-acceptor hydrogen bond interaction. The bond angle at C7 gives a strong indication that H7 center dot center dot center dot S1 contact is repulsive. However, the C5-C7-C8 bond angle = 128.8 (2) degrees, is distorted due to strain induced by double bond linkage at C5=C7. The computational work such as optimized geometry by Density functional theory (DFT), FT-IR, Molecular electrostatic potential (MEP), Frontier Molecular orbitals (FMOs), Mulliken’s population analysis, Nonlinear optical effects (NLO), and Natural bond orbitals (NBO) were analyzed with the aid of Gaussian 03 program using basic set B3LYP/6-311++G (d,p). The proton H-1 and carbon C-13 NMR chemical shifts of molecules were simulated by the gauge-independent atomic orbital (GIAO) manner and also compared with experimental H-1 and C-13 NMR results. The in vitro antioxidant study was carried out in DPPH assay ascorbic acid, a standard drug. The in silico molecular docking, ADMET and toxicity studies were performed by Discovery Studio 4.0.

Strongly fluorescing silver(I) complex of a new thiadiazole ligand: X-ray crystallography, close anagostic interactions and TD-DFT emissive states

A new thiadiazole ligand, N-ethyl-5- (benzo[b]thien-2-yl-)-1,3,4-thiadiazol-2-amine (BTH), was prepared from 3-methyl-1-benzofuran-2-carboxylic acid and N-ethylhydrazinecarbothioamide precursors. Corresponding silver(I) complex, tetrakis(N-ethyl-5-(benzo[b]thien-2-yl-)-1,3,4-thiadiazol-2-amine)silver(I) nitrate [Ag-2(BTH)(4)](NO3)(2) (1), was prepared. The structures of BTH and 1 were characterized by H-1-NMR, C-13-NMR, FT-IR, elemental analysis and HR-MS techniques. Furthermore, molecular structure of 1 was illuminated by X-ray crystallography. Owing to strong anagsotic interaction, crystal structure of the complex revealed an intriguing asymmetric monomer unit even with two same ligands in 2:1 metal-to-ligand stoichiometry. Photoluminescence properties of the complex were investigated by solid and solution media emission measurements. Excited and emissive state behavior of the complex was further analyzed by quantum chemical TD-DFT calculations and natural transition orbital (NTO) analyses.

Bis(benzofurano)pyrrole and hybrid thienopyrrole derivatives for organic thin-film transistors

To develop new element blocks based on thienopyrroles (DTP) units, bis(benzofurano)pyrrole and hybrid thienopyrrole derivatives were synthesized by Buchwald-Hartwing amination methods. Optical absorption, cyclic voltammetry (CV), single-crystal X-ray diffraction analyses and organic thin-film transistor (OTFT) were employed to investigate the structure-activity relationships of the resulting pyrrole derivatives. It was found that the introduction of a benzofuran unit enhances the planarity and conjugation of heteroacenes leading to strong molecular aggregation and denser pi-pi stacking, resulting in better charge transport properties with the hole mobility of 0.025 cm(2)V(-1)s(-1) for the OTFTs.

In continuation of our work on enzyme inhibition, the benzofuran-based-thiazoldinone analogues (1-14) were synthesized, characterized by HREI-MS, H-1 and (CNMR)-C-13 and evaluated for urease inhibition. Compounds 1-14 exhibited a varying degree of urease inhibitory activity with IC50 values between 1.2 +/- 0.01 to 23.50 +/- 0.70 mu M when compared with standard drug thiourea having IC50 value 21.40 +/- 0.21 mu M. Compound 1, 3, 5 and 8 showed significant inhibitory effects with IC50 values 1.2 +/- 0.01, 2.20 +/- 0.01, 1.40 +/- 0.01 and 2.90 +/- 0.01 mu M respectively, better than the rest of the series. A structure activity relationship (SAR) of this series has been established based on electronic effects and position of different substituents present on phenyl ring.
