AgNO3 catalyzed synthesis of 5-substituted-1H-tetrazole via [3+2] cycloaddition of nitriles and sodium azide Dedicated to the memory of late Dr. Tarkeshwar Gupta

An efficient one-pot, convenient catalysis for the synthesis of 5-substituted-1H-tetrazoles is reported. The [3+2] cycloaddition involves various nitriles, sodium azide in refluxing DMF and AgNO3 as catalyst to give corresponding 5-substituted-1H-tetrazoles in good to excellent yields. It is expected that the reaction proceeds via in situ formation of a silver azide species, which participates in coordination of nitrile moiety followed by cycloaddition of azide ion to give tetrazole.

Syntheses of 2-aryl benzothiazoles via photocatalyzed oxidative condensation of amines with 2-aminothiophenol in the presence of bodipy derivatives

A simple, convenient, and efficient new method for synthesis of 2-aryl benzothiazoles under mild conditions with nonmetal catalyst has been developed. Boron-dipyrromethene (BODIPY) dyes were used as photocatalysts for aerobic oxidative reactions of amine with 2-aminothiophenol. The approach will be very useful for the synthesis of benzothiazole derivatives and the development of photocatalytic reactions.

2-amino-4-arylthiazole derivatives as anti-giardial agents: Synthesis, biological evaluation and QSAR studies

A series of seven 2-amino-4-arylthiazoles were prepared following Hantzsch’s modified method under microwave irradiation. A set of 50 derivatives was obtained and the in vitro activity against Giardia intestinalis was evaluated. The results on the biological activity revealed that, in general, the N-(5-bromo-4-aryl-thiazol-2-yl)-acetamide scaffold showed high bioactivity. In particular, compounds 6e (IC50= 0.39 muM) and 6b (IC50= 0.87 muM) were found to be more potent than the positive control metronidazole. Citoxicity and acute toxicity tests performed showed low toxicity and high selectivity of the most active compounds (6e SI = 139, 6b SI = 52.3). A QSAR analysis was applied to a data set of 37 obtained 2-amino-4-arylthiazoles derivatives and the best model described a strongly correlation between the anti-giardiasic activity and molecular descriptors as E2M, RDF115m, F10, MATS6v, and Hypnotic-80, with high statistical quality. This finding indicates that N-substituted aminothiazole scaffold should be investigated for the development of highly selective anti-giardial agent.

Direct C-H carboxylation with carbon dioxide using 1,2,3-triazol-5-ylidene copper(I) complexes

1,2,3-Triazol-5-ylidene copper(I) complexes (tzNHC-Cu) efficiently catalyzed the direct C-H carboxylation of benzoxazole and benzothiazole derivatives with CO2 to give the corresponding esters in excellent yields after treatment with alkyl iodide. The tzNHC copper(I) complex, i.e., [(TPr)CuCl], worked somewhat more effectively than the corresponding imidazol-2-ylidene copper(I) complex [(IPr)CuCl] to give the carboxylation product in higher yields.

Quantum chemical and molecular dynamics simulation studies on inhibition performances of some thiazole and thiadiazole derivatives against corrosion of iron

In the present study, to predict corrosion inhibition performances of 2-amino-4-(4-chlorophenyl)-thiazole (Inh1), 2-amino-4-(4-bromophenyl)-thiazole (Inh2), 4-(2-aminothiazole-4-yl)-phenol (Inh3), 5,5?-(ethane-1, 2-diyldisulfanediyl) bis-(1,3,4-thiadiazole-2-amine) (Inh4), 5,5?-(propane-1,3-diyldisulfanediyl) bis-(1,3,4-thiadiazole-2-amine) (Inh5) against corrosion of Fe metal, density functional theory (DFT) calculations and molecular dynamics simulations approach were performed on these mentioned molecules. Firstly, quantum chemical parameters such as the highest occupied molecular orbital energy (EHOMO), lowest unoccupied molecular orbital energy (ELUMO), the energy gap between ELUMO and EHOMO (DeltaE), chemical hardness, softness, electronegativity, proton affinity, global electrophilicity, global nucleophilicity and total energy (sum of electronic and zero-point energies) were calculated and discussed with the help of HF/SDD, HF/6-311G, HF/6-31 ++G, B3LYP/SDD, B3LYP/6-311G and B3LYP/6-31 ++G methods. Then, we calculated binding energies on Fe(110) surface of aforementioned thiazole and thiadiazole derivatives to investigate the strength of the interactions between metal surface and these molecules. The theoretical data obtained are in good agreement with the experimental inhibition efficiency results earlier reported.

Surface-assisted laser desorption/ionization mass spectrometry on nanostructured silicon substrates prepared by iodine-assisted etching

Surface-assisted laser desorption/ionization (SALDI) is a matrix-free mass spectrometry (MS) approach that utilizes the unique properties of a nanostructured surface to promote desorption and ionization. However, there are still questions on what constitutes a suitable SALDI substrate for mass spectrometric application. A range of SALDI substrates prepared by anodization with an oxidizing electrolyte was investigated. The laser desorption/ionization (LDI) performance was examined on a reflectron time-of-flight (ToF) mass spectrometer. The physicochemical properties of the substrates were characterized by a number of surface analysis techniques including scanning electron microscopy (SEM), atomic force microscopy (AFM), secondary ion mass spectrometry (SIMS), X-ray photoelectron spectroscopy (XPS) and water contact angle measurement. Examination of surface cleaning technologies and methods for surface chemical modification were carried out. Correlation between the substrate physicochemical properties and the LDI performance was determined. It was found that only the substrate, which had a thick nanostructured layer, was effective for LDI-MS. SALDI substrate was found to have a high surface potential. However, this unique property offered no advantage for the application of LDI-MS. Surface chemistry is also an important factor in affecting the LDI performance. Plasma etching can effectively remove the surface contamination but it also increases the thickness of the oxide layer. Fluorine and hydroxyl termination is advantageous. Fluorine passivation increases the surface hydrophobicity, which confines the analyte solution droplet to a smaller area and also withdraws the electronic density from the surface, and acidifies the surface Si-OH moieties, which is believed a major proton source. The effect of laser etching was investigated by SIMS and XPS imaging and provided new insight of the SALDI ionization mechanism.

A general and efficient method for a metal-free one-pot synthesis of highly substituted fused imidazole-containing 5,5- and 5,6-fused bicyclic heterocycles is described. Starting from commercially available substrates and reagents, the reaction proceeds through two C-N bond formations and an oxidative dehydrogenation to form highly substituted products in good to excellent yield.

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.Recommanded Product: Ethyl 2-(benzo[d]thiazol-2-yl)acetate, you can also check out more blogs about29182-42-1
