A FACILE SYNTHESIS AND ANTIBACTERIAL ACTIVITY OF NOVEL QUINOXALINE-BENZOFURAN HYBRIDS

In the present work, a simple and facile synthesis of a series of new type of quinoxaline-benzofuran hybrids, i.e., 3-(benzofuran-2-yl)quinoxaline-2-carboxylic acids has been achieved using the newly-synthesized ethyl 3-bromomethylquinoxaline-2-carboxylate as substrate through ultrasound-assisted one-pot sequential Rap-Stoermer type reaction with various salicylaldehydes followed by ester hydrolysis. A preliminary screening for their antibacterial activities against five bacterial strains revealed that compounds with tert-butyl and halo (Cl and Br) substituents exhibited promising inhibitory activity against B. subtilis with the MIC values of 15.625 and 7.8125 mu g/mL, respectively, being equipotent or even better than the reference Ciprofoxacin.

Design, synthesis, and biological evaluation of novel 4H-chromen-4-one derivatives as antituberculosis agents against multidrug-resistant tuberculosis

A series of 4H-chromen-4-one derivatives obtained by scaffold morphing of the benzofuran compound, TAM16, were tested for antitubercular activity. Compound 8d was active against drug-sensitive and multidrug-resistant tuberculosis. A preliminary druggability evaluation showed that compound 8d displayed favorable mouse and human microsomal stability, low cytotoxicity, and acceptable oral bioavailability. An in vivo study indicated that compound 8d exhibited modest efficacy in an acute mouse model of TB after 3 weeks of treatment. Thus, 8d is a promising antituberculosis lead compound.

Enantioselective Synthesis of Benzofuran-Fused N-Heterocycles via Chiral Squaramide Catalyzed [4+2] Cyclization of Azadienes with Azlactones

An asymmetric cyclization reaction of azadienes and azlactones was investigated by employing a Cinchona squaramide catalyst, which could afford a series of benzofuran-fused six-membered heterocycles containing a alpha,alpha-disubstituted amino acid unit in a highly diastereoselective (>20:1 dr) and enantioselective (up to 99% ee) manner with good to excellent yields (up to 92%). A plausible pathway was proposed to explain the reaction process.

Optimization of the Reaction Conditions for the Synthesis of Dihydrobenzofuran Neolignans

We have optimized the experimental conditions for the silver(I)-promoted oxidative coupling of methyl p-coumarate (I) and methyl ferulate (II), which is the most frequently used methodology to synthesize the bioactive dihydrobenzofuran neolignans 1 ((+/-)-trans-dehydrodicoumarate dimethyl ester) and 2 ((+/-)-trans-dehydrodiferulate dimethyl ester). Most of the tested conditions affected the conversion (i.e., the consumption of I and II) and the selectivity (i.e., the percentage of I and II that was converted into 1 and 2, respectively), so the optimized conditions were the ones that afforded the best balance between conversion and selectivity. Silver(I) oxide (0.5 equiv.) is the most efficient oxidant agent amongst the silver(I) reagents that were tested to convert methyl esters I and II into compounds 1 and 2, respectively. Acetonitrile, which has not yet been reported as a solvent for this reaction, provided the best balance between conversion and selectivity, besides being greener than other solvents that are more often employed (e.g., dichloromethane and benzene). Under the optimized conditions, the reaction time decreased from 20 to 4 h without significantly impacting the conversion and selectivity.

Heteroaromatic rings as linkers for quercetin-based dye-sensitized solar cell applications: a TDDFT investigation

The electronic properties of quercetin (Q)-pi-cyanoacrylic acid (CNA) dye molecules using heteroaromatic rings, namely cyclopentadiene (F1), furan (F2), pyrrole (F3), thiophene (F4), oxazole (F5), imidazole (F6), thiazole (F7), isoindene (FF1), benzofuran (FF2), indole (FF3), benzothiophene (FF4), benzoxazole (FF5), benzimidazole (FF6), and benzothiazole (FF7), as pi-linkers are studied for the first time using Time-Dependent Density Functional Theory (TDDFT) with dimethyl sulfoxide (DMSO) as solvent to predict their excitation energy, absorption wavelength, oscillator strength, light harvesting efficiency, and exciton binding energy. The charge transfer and charge regeneration in the ground and excited states of the dyes are established. The photon to electron energy transfer from the dye (quercetin) to the semiconductor (TiO2) surface is analyzed based on intramolecular charge transfer. The results of the electron transfer studies on these newly designed dyes could be used to enhance the performance of resulting dye-sensitized solar cells.

Palladium-catalyzed Tsuji-Trost-type reaction of benzofuran-2-ylmethyl acetates with nucleophiles

The palladium-catalyzed benzylic-like nucleophilic substitution of benzofuran-2-ylmethyl acetate with N, S, O and C soft nucleophiles has been investigated. The success of the reaction is dramatically influenced by the choice of catalytic system: with nitrogen based nucleophiles the reaction works well with Pd-2(dba)(3)/dppf, while with sulfur, oxygen and carbo-nucleophiles [Pd(eta(3)-C3H5)Cl](2)/XPhos is more efficient. The regiochemical outcome shows that the nucleophilic substitution occurs only on the benzylic position of the eta(3)-(benzofuryl)methyl complex. The high to excellent yields and the simplicity of the experimental procedure make this protocol a versatile synthetic tool for the preparation of 2-substituted benzo[b]furans.

(4+3) cycloadditions of allenyl ether-derived oxygen-stabilized oxyallyls with furans

(4 + 3) cycloadditions between allenyl ethers and furans are described. The reaction features an in situ formation of oxygen-stabilized oxyallyls via epoxidations of allenyl ethers in the presence of H2PO4-. The multiple interactions between the oxygen-stabilized oxyallyl species and H2PO4- were studied using DFT calculations for rationalization of the regio- and diastereoselectivity of this cycloaddition. The utilities of this cycloaddition have been demonstrated by converting the (4 + 3) cycloadduct into the cyclohepta[b]benzofuran skeleton of frondosin B in two steps.
