Design and Synthesis of New Benzofuran-1,2,3-Triazole Hybrid Preservatives and the Evaluation of Their Antifungal Potential Against White and Brown-Rot Fungi

A series of novel benzofuran-1,2,3-triazole hybrids were synthesized and investigated as fungicidal preservatives. The compounds were evaluated for their antifungal potential against white-rot (Trametes versicolor), dry brown-rot (Poria placenta), and wet brown-rot (Coniophora puteana and Gloeophyllum trabeum) fungi, at different concentrations (500 ppm and 1000 ppm). The tests of the final products (8a, 8b, 8c, 8d, 8e, 8f, and 8g) demonstrated that compound N-((1-(4-fluorobenzyl)-1H-1,2,3-triazol-4-yl)methyl)benzofuran-2-carboxamide (8f) at a concentration of 500 ppm was the most active against wet brown-rot C. puteana (23.86% inhibition) and G. trabeum (47.16% inhibition) fungi. However, testing demonstrated that compounds 8a, 8b, 8c, 8d, and 8g at a concentration of 500 ppm did not exhibit acceptable antifungal effects against white-rot T. versicolor and dry brown-rot P. placenta fungi.

Synthesis of Elaborate Benzofuran-2-Carboxamide Derivatives through a Combination of 8-Aminoquinoline Directed C-H Arylation and Transamidation Chemistry

Herein, we present a short and highly modular synthetic route that involves 8-aminoquinoline directed C-H arylation and transamidation chemistry, and which enables access to a wide range of elaborate benzofuran-2-carboxamides. For the directed C-H arylation reactions, Pd catalysis was used to install a wide range of aryl and heteroaryl substituents at the C3 position of the benzofuran scaffold in high efficiency. Directing group cleavage and further diversification of the C3-arylated benzofuran products were then achieved in a single synthetic operation through the utilization of a one-pot, two-step transamidation procedure, which proceeded via the intermediate N-acyl-Boc-carbamates. Given the high efficiency and modularity of this synthetic strategy, it constitutes a very attractive method for generating structurally diverse collections of benzofuran derivatives for small molecule screening campaigns.

Synthesis of hybrid polycycles containing fused hydroxy benzofuran and 1H-indazoles via a domino cyclization reaction

A stoichiometry controlled domino cyclization reaction of hydrazone and p-benzoquinone to an angularly fused 3H-benzofuro[3,2-e]indazole core with an embedded oxygenated dibenzofuran framework under mild reaction conditions is disclosed. The reaction involves palladium catalyzed 5-hydroxy-1H-indazole formation followed by TFA mediated [3+2] annulation between the in situ formed 5-hydroxy-1H-indazole and p-benzoquinone. The developed method is attractive because of the concomitant formation of two heterocyclic rings with consecutive multiple bond forming events that include two C-C, one C-N and one C-O bonds. Spectroscopic and theoretical studies of the blue emissive benzofuroindazole derivatives have also been described.

Multi-step parallel synthesis enabled optimization of benzofuran derivatives as pan-genotypic non-nucleoside inhibitors of HCV NS5B

In a lead optimization effort towards NS5B NNI inhibitors, two multi-step parallel libraries were designed and successfully synthesized. Through this effort we discovered compound 9B, which achieved rigorous and delicate balance of inhibition across the common genotypes and mutants with < 10 nM potency. In addition, the bicyclic compounds 9B exhibited improved FASSIF solubility over the tetracyclic compound MK-8876. This strategic approach demonstrated that, even within limited reaction scope, multi-step parallel libraries could provide access to more complex chemical space. This expedient access facilitates diverse, purpose-driven optimization of SAR and physicochemical properties.

Palladium complexes with an annellated mesoionic carbene (MIC) ligand: catalytic sequential Sonogashira coupling/cyclization reaction for one-pot synthesis of benzofuran, indole, isocoumarin and isoquinolone derivatives

Two Pd(II) complexes (1 and 2) featuring a fused pi-conjugated imidazo[1,2-a][1,8]naphthyridine-based mesoionic carbene ligand have been synthesized and structurally characterized. Both complexes effectively catalyze the one-pot synthesis of benzofuran starting from phenylacetylene and 2-iodophenol under mild conditions. Complex 1 is found to be an excellent catalyst for the straightforward access to a library of benzofuran, indole, isocoumarin and isoquinolone derivatives by the reaction of terminal alkynes with 2-iodo derivates of phenol, N-methyl aniline, benzoic acid and N-methyl benzamide, respectively. The general utility of the catalytic method is demonstrated using a variety of diversely substituted terminal alkynes and the corresponding desired products are obtained in good to excellent yields. On the basis of control experiments, a two-cycle mechanism is proposed which involves the Sonogashira coupling of 2-iodo derivatives with alkynes and the subsequent cyclization of the corresponding 2-alkynyl compounds.

Structural, spectroscopic and computational investigations on (4,6-dimethyl-benzofuran-3-yl)-acetic acid hydrazide

The present work investigates structural and spectroscopic characteristics of (4,6-dimethyl-benzofuran-3-yl)-acetic acid hydrazide (4DBAH) through different spectroscopic methods (Infrared, Raman, and NMR) and quantum chemical computations. The quantum chemical computations are done with adequate level of theory using B3LYP from density functional with 6-311++G(d,p) basis set. Conformational analysis is performed to identify the structure corresponding to local minima and local maxima from the potential energy surface (PES).The theoretically simulated and Raman wavenumbers are compared with experimental data. The complete wavenumber assignments are accomplished by the potential energy distribution (PED) of individual vibrational modes. The experimental H-1 and C-13 NMR chemical shifts are investigated and then compared with computed NMR data. The AIM and NCI analysis gives more insights into the nature of different types of interactions, both attractive and repulsive nature present in the molecule. In addition, several analyses such as NBO, NLO, FMO, MEP and thermodynamic properties have also been conducted to determine the nature of the 4DBAH. (C) 2020 Published by Elsevier B.V.

Recent Updates on Anti-Inflammatory and Antimicrobial Effects of Furan Natural Derivatives

The furan nucleus is found in a large number of biologically active materials. In recent years, many natural furan derivatives were isolated and their biological effects were investigated. In this review, we focused on the anti-inflammatory and antimicrobial effects of some natural furans and discussed their effects on the immune system. Our investigation revealed that furan natural derivatives have effective antioxidant activities and exert regulatory effects on various cellular activities by modifying some signaling pathways such as MAPK (mitogen-activated Protein Kinase) and PPAR-gamma (peroxisome proliferator-activated receptor gamma). The antimicrobial activity of these natural compounds was performed through selective inhibition of microbial growth and modification of enzymes. Further studies are needed for isolation and detection of different furan derivatives from natural compounds and investigation of their precise mechanisms for revealing health beneficial effects of these compounds.

Cs2CO3-Mediated Rapid Room-Temperature Synthesis of 3-Amino-2-aroyl Benzofurans and Their Copper-Catalyzed N-Arylation Reactions

Cs2CO3 in dimethylformamide (DMF) is a perfect combination for the rapid room-temperature synthesis of 3-amino-2-aroyl benzofuran derivatives from the reaction of 2-hydroxybenzonitriles and 2-bromoacetophenones in good to excellent yields. Using this one-pot C-C and C-O bond-forming strategy, we prepared a series of 3-amino-2-aroyl benzofuran derivatives within a very short time (10-20 min). This method was also found suitable for gram-scale synthesis. Benzofurans (3) obtained by this Cs2CO3-mediated methodology were then further explored for the development of a tunable base- and ligand-free copper-catalyzed N-arylation methodology using arylboronic acids for the easy access of either mono- or bi-N-aryl derivatives of aminobenzofurans at ambient temperature. The reaction of 3 with malononitrile in DMF medium under microwave heating conditions provided highly fluorescent conjugated alkenes and novel pyridine-fused benzofurans.

Benzofuran-2-acetic esters as a new class of natural-like herbicides

BACKGROUND In recent decades, the use of synthetic herbicides has been increasing, mainly in emerging countries. However, their intensive and indiscriminate application is a major cause of environmental pollution and human health injury. Therefore, there is an increasing need to develop new herbicides with safer toxicological and environmental profiles. A promising strategy is to synthesize new molecules containing the core of natural products as a template for the production of ‘bio-inspired’ or ‘natural-like’ herbicides. RESULTS The potential herbicidal activity of some benzofuran-2-acetic esters was assessed in vitro on Arabidopsis thaliana, a model species. All five molecules (M1-M5) showed significant phytotoxic activity, reducing both shoot and root system at low concentrations. In particular, methyl 2-(5-methoxybenzofuran-2-yl)hexanoate (M3) exhibited the highest phytotoxicity displayed against two crops and weeds, monocots (Zea mays L. and E. crus-galli) and dicots (Lactuca sativa L. and Amaranthus retroflexus L.). The M3 activity was also compared with glyphosate, a common herbicide, showing a lower but similar activity. Moreover, the results evidenced that M3 was more effective in post-emergency. CONCLUSION Readily synthesizable benzofuran-2-acetic esters possessing the benzofuran ring as ‘bio-inspired’ core, show significant herbicidal activity making them very efficient even at low concentrations. They can be sprayed in liquid form, and the addition of adjuvants can improve penetration through the leaf cuticle. These results confirm the importance of these molecules as models for the development of new natural-like herbicides. (c) 2019 Society of Chemical Industry

A ZnI2-catalyzed regioselective cascade 1,4-conjugate addition/5-exo-dig annulation pathway for one-pot access to heterobiaryl frameworks

Facile access to pi-extended heterobiaryl compounds via a non-cross-coupling strategy has been achieved. In the presence of an inexpensive ZnI2 catalyst and versatile propargylamine and beta-naphthol (or beta-naphthylamine and beta-naphthyl mercaptan) starting materials, a variety of sterically hindered heterobiaryl frameworks can be easily obtained. The present catalytic system offers excellent selectivity, good-to-excellent product yields, and good functional group tolerance including, for instance, -CN, -COOH, -C(O)R, -Br and -Cl groups. This cyclization process is proposed to proceed via in situ generated alkynyl o-quinone methides (o-AQMs), following a cascade intermolecular 1,4-conjugate addition/5-exo-dig annulation/1,3-H shift pathway.
