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.

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.

Ultrasound Assisted Synthesis of 2-Substituted Benzofurans via One-Pot and Sequential Method: Their In Vitro Evaluation

Background: The 2-substituted benzofuran framework has attracted enormous attention due to its presence in a range of bioactive compounds and natural products. While various methods for the synthesis of 2-substituted benzofuran derivatives are known, several of them suffer from certain drawbacks. Objective: The main objective of this work was to explore a series of 2-(het)aryl substituted benzofurans derivatives for their cytotoxic properties against cancer cell lines in vitro. Methods: In our efforts, we have developed a one-pot synthesis of this class of compounds via sequential C-C coupling followed by C-Si bond cleavage and subsequent tandem C-C/C-O bond-forming reaction under ultrasound irradiation. The methodology involved coupling of (trimethylsilyl)acetylene with iodoarenes in the presence of 10% Pd/C-Cul-PPh3-Et3N in MeOH followed by treating the reaction mixture with K2CO3 in aqueous WON and finally coupling with 2-iodophenol. A variety of 2-substituted benzofurans were synthesized using this methodology in good yield. All the synthesized compounds were tested in vitro against two cancer cell lines, e.g. MDAMB-231 and MCF-7 cell lines subsequently against SIRT1. Results: The benzofuran derivative 3m showed encouraging growth inhibition of both MDAMB-231 and MCF-7 cell lines and significant inhibition of SIRT1. The compound 3m also showed a concentration-dependent increase in the acetylation of p53. Conclusion: Our efforts not only accomplished a one-pot and direct access to 2-(het)aryl substituted benzofurans but also revealed that the benzofuran framework presented here could be a potential template for the identification of potent inhibitors of SIRT1.

Study of Metal Ion Removal from Aqueous Systems Using Magnetic Nanostructures Based on Functionalized Poly(Benzofuran-co-Arylacetic Acid)

Metal pollution has become a worldwide problem, mainly because of the toxicity, effects on living organisms, and the impact on the food chain and the quality of drinking water. Researchers have been focusing on developing new materials through green chemistry methods in order to remove these pollutants from the environment. In the recent decades, due to their unique properties, magnetic nanostructures containing functionalized polymers as shells have been demonstrated to be useful in water and wastewater treatment for this application. In this study, we report the synthesis and characterization of hybrid magnetic core-shell nanostructures including magnetite as the inorganic core and poly(benzofuran-co-arylacetic acid) functionalized with N alpha, N alpha’-bis(carboxymethyl)-L-lysine as the organic shell. These nanomaterials were used in the adsorption of different metal ions from aqueous solutions and contaminated water samples collected from Rosia River (Rosia Montana, Romania), representing attractive alternatives for water and/or wastewater treatment. The properties of the magnetic hybrid nanostructures were investigated by Fourier-transform infrared spectroscopy (FTIR), transmission electron microscopy (TEM), scanning electron microscopy (SEM), thermogravimetric analysis (TGA), magnetization measurements. The heavy metal concentrations in aqueous solutions were determined by flame atomic absorption spectrometry (FAAS).

Synthesis and evaluation of methoxy substituted 2-benzoyl-1-benzofuran derivatives as lead compounds for the development adenosine A(l) and/or A(2A) receptor antagonists

A series of fourteen methoxy substituted 2-benzoyl-1-benzofuran derivatives were synthesised and their affinities determined for adenosine A(1) and A(2A) receptors via radioligand binding assays to establish the structure activity relationships pertinent for A(1) and A(2A) affinity. Compound 3j (6,7-dimethoxybenzofuran-2-yl)(3-methoxyphenyl) methanone exhibited A(1) affinity (A(1)K(i) (rat) = 6.880 mu M) as well as A(2A) affinity (A(2A)K(i) (rat) = 0.5161 mu M). Compounds 3a-b & 3i-k exhibited selective affinity towards A(1) with K-i values below 10 mu M. The results indicate that C6,7-diOCH(3) substitution on ring A in combination with meta (C3′)-OCH3 substitution on ring B is beneficial for A(1) and A(2A )affinity and activity. Compounds 3a-b & 3j-k showed low cytotoxicity. Upon in vitro and in silico evaluation, compound 3j may be considered lead-like (i.e. a molecular entity suitable for optimization) and, thus, of value in the design of novel, potent and selective adenosine A(1) and A(2A) receptor antagonists.

Site-selective remote C(sp(3))-H heteroarylation of amides via organic photoredox catalysis

Radical translocation processes triggered by nitrogen-centered radicals (NCRs), such as 1,5-hydrogen atom transfers (1,5-HAT), demonstrated by the well-established Hofmann-Loffler-Freytag (HLF) reaction, provide an attractive approach for the controllable and selective functionalization of remote inert C(sp(3))-H bonds. Here we report an amidyl radical-triggered site-selective remote C(sp(3))-H heteroarylation of amides under organic photoredox conditions. This approach provides a mild and highly regioselective reaction affording remote C(sp(3))-H heteroarylated amides at room temperature under transition-metal free, weakly basic, and redox-neutral conditions. Non-prefunctionalized heteroarenes, such as purines, thiazolopyridines, benzoxazole, benzothiazoles, benzothiophene, benzofuran, thiazoles and quinoxalines, can be alkylated directly. Sequential and orthogonal C-H functionalization of different heteroarenes by taking advantage pH value or polarity of radicals has also been achieved. DFT calculations explain and can predict the site-selectivity and reactivity of this reaction. This strategy expands the scope of the Minisci reaction and serves as its alternative and potential complement.

A Green Mechanochemical One-Pot Three-Component Domino Reaction Synthesis of Polysubstituted Azoloazines Containing Benzofuran Moiety: Cytotoxic Activity Against HePG2 Cell Lines

A one-pot procedure for the synthesis of azolopyrimidine derivatives by a three-component reaction of beta-ketosulfone, aldehyde, and 2-aminoben-zimidazole over synthetic magadiite clay (SMC-H) under ball milling in the absence of any solvent and additive has been developed. The catalyst was re-used for consequent reactions. The novel manufactured compounds were verified for HePG2 cell development inhibition. A pronounced inhibitory effect on the growth of HePG2 cell line was recorded. This protocol offers a broad scope for an access to a variety of diversely substituted azolopyrimidines of high inhibition activity against HePG2 cell line. The use of non-hazardous organic solvent, ball milling, cost efficiency, recyclability of the catalyst up to six runs without appreciable loss of activity, and high yields of products make this procedure greener.

Synthesis of New 4-Oxo-Tetrahydroindol Derivatives by Using Chemical and Microbial Biotransformation Methods

An efficient method for the preparation of 4-oxo-4,5,6,7-tetrahydroindoles was successfully applied to the synthesis of N-substituted 4-oxo-4,5,6,7-tetrahydroindoles (4) and (5) for the first time. Manganese(III) acetate-mediated acetoxylation of (2) produced 4,5,6,7-tetrahydro-4-oxo-7,7-dimethyl benzofuran-5-yl acetate (3) for the first time in the literature. Then 4,5,6,7-tetrahydro-4-oxo-7,7-dimethyl benzofuran-5-yl acetate was converted to its indole derivative (4) via benzyl amine. Thus, 1-benzyl-5-hydroxy-7,7-dimethyl-6,7-dihydro-1H-indol-4(5H)-one (4) was obtained in good yields. Furthermore, biotransformation of pharmacologically interesting compounds such as 5-hydroxy-7,7-dimethyl-6,7-dihydro-1H-indol-4-(5H)-one (5) were also obtained by biotransformation reaction using Aspergillus niger.

Evaluation of Synthesized Ester or Amide Coumarin Derivatives on Aromatase Inhibitory Activity

Aromatase inhibitors are effective for the treatment of diseases such as breast cancer, which has led to an increase in their demand. However, only a limited number of aromatase inhibitor drugs are currently being marketed. In addition, considering the important aspect of drug resistance, the development of newer drug types is required. We have been developing inhibitors with backbone structures that differ from existing aromatase inhibitors. In this regard, we previously reported that diethylaminocoumarin dimers and thiazolyl coumarin derivatives possess strong aromatase inhibiting capabilities. In this study, we further examined the structure activity relationships of coumarin derivatives synthesized from thiazolyl coumarin derivatives and their aromatase inhibiting capabilities. Consequently, amide coumarin N-benzhydry1-7-(diethylamino)2-oxo-2H-chromene-3-carboxamide (IC50 values 4.5 mu M) is inhibitor of aromatase. This inhibitor was found to be comparable aromatase inhibitory activity to the 1st generation aromatase inhibitor aminoglutethimide (3.2 mu M). Substitution of the amide group on the amide coumarin derivative affects the aromatase inhibiting activity. Our findings suggest that the structure of each substituent changes the orientation of the compound in the active site of aromatase, thus creating a difference in their activities.
