Synthesis of Benzo[b]azocin-2-ones by Aryl Amination and Ring-Expansion of alpha-(Iodophenyl)-beta-oxoesters

Transformation of beta-oxoesters with PhI(OCOCF3)(2) leads to alpha-(ortho-iodophenyl)-beta-oxoesters. These materials are the starting point for the synthesis of 6-carboxybenzo[b]azocin-2-ones by a sequence of aryl amination and ring transformation. This reaction sequence starts with copper-catalyzed formation of N-alkyl anilines from the iodoarenes and primary amines in the presence of K3PO4 as stoichiometric base. The intermediate products underwent ring transformation by addition of the nitrogen into the carbonyl group of the cycloalkanone, furnishing benzo-annulated eight-membered ring lactams. Under the same reaction conditions, the cyclohexanone and cycloheptanone derivatives gave no aminated products, but ring-transformed to benzofuran derivatives. The title compounds of this investigation contain two points for further diversification (the lactam nitrogen and the carboxylate function), thus, the suitability of this compound class as a scaffold was proven by appropriate functionalizations. The first series of derivatizations of the scaffold was initiated by hydrogenolytic debenzylation of N-benzyl derivative to provide the NH-congener, which could be deprotonated with LDA and alkylated at nitrogen to give further examples of this compound class. Secondly, the ester function was submitted to saponification and the resulting carboxylic acid could be amidated using HATU as coupling reagent to furnish different amides.

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. Safety of 3-Furanmethanol.

Synthesis, DFT computational insights on structural, optical, photoelectrical characterizations and spectroscopic parameters of the novel (2E)-3-(4-methoxy-5-oxo-5H-furo[3, 2-g]chromen-6-yl)acrylonitrile(MOFCA)

Reaction of 6-formylvisnagin (1) with cyanoacetic acid in dry pyridine afforded the novel (2E)-3-(4methoxy-5-oxo-5H-furo[3,2-g]chromen-6-yl)acrylonitrile (2, MOFCA). The chemical structure of the prepared compound was determined by the elemental analysis and spectral data. The individual emulation characteristics of compound (2, MOFCA), were accomplished by DFT, and TD-DFT/B3LYP, at 6-311 ++ G (d, p). The computational results detect the most stable structure of MOFCA, depending on the positions of the methoxy (O-CH 3) group, within change in dihedral angle. FT-IR spectroscopy was applied for the vibrational spectral analysis. Using frontier molecular orbital (FMO) analysis, various spectroscopic and quantum chemical parameters are discussed. The absorption energies, oscillator strength, and electronic transitions of compound (2, MOFCA), have been derived at TD-DFT/CAM-B3LYP/6-311++ G (d,p) computations utilizing a PCM and measured in different polar and non-polar solvents experimentally in UV-Vis spectra. The output of the computation shows accurate agreement between theoretical spectra and practical spectra for the title compound. NLO analysis was computed at the identical plane of theory which are, alpha; Delta alpha, and first-order , the hyper-Rayleigh scattering (beta HRS) and the depolarization ratio (DR), were shown promising optical properties. The plots of natural bonding orbital (NBO), thermochemical parameters and the molecular electrostatic potential surfaces (MEPS) have been computed. All the computations in the gas phase have been completed. (C) 2020 Elsevier B.V. All rights reserved.

Recent Developments in C-H functionalisation of Benzofurans and Benzothiophenes

Benzofurans and benzothiophenes are important pharmaceutical motifs, appearing in a broad range of small molecule therapeutic classes. Often overlooked by synthetic methodologists in favour reactions of the analogous indole bicyclic system, there is nevertheless a plurality of approaches to effecting benzofuran and benzothiophene C-H functionalisations. In this review, we summarise progress in this area over the past five years, including 1) alkylations, 2) arylations and heteroarylations, 3) carboxylations, carbamoylations, and C-heteroatom bond formations and 4) cyclisations.

Synthesis of aurone derivatives on the basis of 2,4,6-trihydroxytoluene

2,4,6-Trihydroxytoluene (2-methylphloroglucinol) was used as starting material for the first synthesis of several (Z)-2-arylidene-4,6-dihydroxy-7-methylaurones, including a synthetic analog of the natural 7-methylaureusidin, which is currently obtained mainly from the extract of sedge capitata (Cyperus capitatus). It was shown that the reaction of 2,4,6-trihydroxytoluene with chloroacetonitrile occurred regioselectively, with the formation of 4,6-dihydroxy-7-methylbenzofuran-3(2H)-one, the treatment of which with substituted benzaldehydes gave high yields of the target compounds.

Spiroindolone Analogues as Potential Hypoglycemic with Dual Inhibitory Activity on alpha-Amylase and alpha-Glucosidase

Inhibition of alpha-amylase and alpha-glucosidase by specified synthetic compounds during the digestion of starch helps control post-prandial hyperglycemia and could represent a potential therapy for type II diabetes mellitus. A new series of spiroheterocyclic compounds bearing oxindole/benzofuran/pyrrolidine/thiazolidine motifs were synthesized via a 1,3-dipolar cyclo-addition reaction approach. The specific compounds were obtained by reactions of chalcones having a benzo[b]furan scaffold (compounds 2a-f), with a substituted isatin (compounds 3a-c) and heterocyclic amino acids (compounds 4a,b). The target spiroindolone analogues 5a-r were evaluated for their potential inhibitory activities against the enzymes alpha-amylase and alpha-glucosidase. Preliminary results indicated that some of the target compounds exhibit promising alpha-amylase and alpha-glucosidase inhibitory activity. Among the tested spiroindolone analogues, the cycloadduct 5r was found to be the most active (IC50 = 22.61 +/- 0.54 mu M and 14.05 +/- 1.03 mu M) as alpha-amylase and alpha-glucosidase inhibitors, with selectivity indexes of 0.62 and 1.60, respectively. Docking studies were carried out to confirm the binding interaction between the enzyme active site and the spiroindolone analogues.

The modelling of metabolic activation of the benzofuran nucleus is important to obtain eco-sustainable degradation methods and to understand the related mechanisms. The present work reports the catalytic oxidation of benzofuran, 2-methylbenzofuran, and 3-methylbenzofuran by hydrogen peroxide, at room temperature, in the presence of different Mn(III) porphyrins as models of cytochrome P450 enzymes. Conversions above 95% were attained for all the substrates.
