Stereocontrolled Ring-Opening of a Hindered Sulfamidate with Nitrogen-Containing Aromatic Heterocycles: Synthesis of Chiral Quaternary Imidazole Derivatives

This paper explores the role of a hindered cyclic sulfamidate derived from alpha-methylisoserine as an electrophile in a nucleophilic displacement reaction with nitrogen-containing aromatic heterocycles. Several imidazoles and pyrazole were tested as nucleophiles in the absence of an additional base to give the corresponding ring-opening compounds: We show that the process takes place by inversion of the configuration of the quaternary electrophilic center, retaining the enantiomeric excess of the starting sulfamidate. This reaction opens the way to obtain important quaternary imidazole derivatives such as an innovative type of bis-amino add related to histidinoalanine and a novel alpha,alpha-disubstituted beta-amino acid(beta(2,2)-amino acid)

Clay-Supported 2-Phenyl-1H-Imidazole Derivatives for Heterogeneous Catalysis of Henry Reaction

Six derivatives (1-6) of 2-phenyl-1H-imidazole were tested as catalysts of Henry reaction. Three new (4-6) 2-phenyl-1H-imidazole derivatives, differently substituted (thio)ureas, were synthesized and determined by H-1 NMR and IR spectroscopy and elemental analysis. Two types of catalysis, homogeneous and heterogeneous, were examined and compared. Clay minerals Ca-MMT and Cu-MMT were used as solid supports for heterogeneous catalysis. The best results were obtained using compound 2 under conditions of heterogeneous method D from the point of view of yield and reaction time.

Unusual methylene transfer in reactions of Simmons-Smith reagent with 1,3-diazabuta-1,3-dienes: synthesis of functionalised imidazole derivatives

The reactions of Simmons-Smith reagent with 1-aryl-2-phenyl-4-methylthio-4-secondary amino 1,3-diazabuta-1,3-dienes 1 underwent an unusual 1,4-methylene transfer resulting in the formation of 1-aryl-2-phenyl-4-secondary amino imidazoles 4. Whereas, its reactions with 1-aryl-2-phenyl-4-secondary amino-1,3-diazabuta-1,3-dienes 8 underwent an initial 1,2-methylene transfer leading to an aziridine intermediate which rearranges to 1-aryl-4-phenyl-imidazoles 11.

Synthesis and antibacterial activity of novel and potent DNA gyrase inhibitors with azole ring

The 4-piperidyl moiety and the pyrazole ring in 1-(3-chlorophenyl)-5-(4-phenoxyphenyl)-3-(4-piperidyl)pyrazole 2, which has previously shown improved DNA gyrase inhibition and target-related antibacterial activity, were transformed to other groups and the in vitro antibacterial activity of the synthesized compounds was evaluated. The selected pyrazole, oxazole and imidazole derivatives showed moderate inhibition against DNA gyrase and topoisomerase IV with similar IC50 values (IC50 = 9.4-25 mug/mL). In addition, many of the pyrazole, oxazole and imidazole derivatives synthesized in this study exhibited potent antibacterial activity against quinolone-resistant clinical isolates and coumarin-resistant laboratory isolates of Gram-positive bacteria with minimal inhibitory concentration values equivalent to those against susceptible strains.

Artificial neural networks for prediction of antibacterial activity in series of imidazole derivatives

Artificial neural networks (ANNs) have been applied for the quantitative structure-activity relationships (QSAR) studies of antibacterial activity against Escherichia coli, Serratia marcescens, Proteus vulgaris, Klebsiella pneumoniae and Pseudomonas aeruginosa of a large series of new imidazole derivatives. Antibacterial activity against individual bacteria, expressed as logarithm of reciprocal of the minimal inhibitory concentrations, log 1/MIC, has been related to a number of physicochemical and structural parameters of the imidazole derivatives investigated. Molecular descriptors of agents were obtained by quantum-chemical calculations combined with molecular modelling and from respective structure fragment reference data (e.g., log P). A high correlation resulted between the predicted from ANN model antibacterial activity, log 1/MICANN, and that from biological experiments, log 1/MICexp, both for the data used in learning and in the testing sets of imidazoles. Correlation coefficient, R, depending oil the type of bacteria and Structural subset of analysed imidazole compounds, varies front 0.875 to 0.969. The applicability of ANNs has been demonstrated for the prediction of pharmacological potency of new imidazole derivatives based on their structural descriptors generated exclusively by calculation chemistry.

A novel approach to study the inclusion mechanism of imidazole derivatives in micellar chromatography

A chromatographic approach was proposed to describe the existence of surfactant micelles in a surfactant/hydroorganic phosphate buffer mobile phase. Using this mixture as a mobile phase, a novel mathematical theory is presented to describe the inclusion mechanism of imidazole derivatives in surfactant micelles. Using this model, enthalpy, entropy and the Gibbs free energy were determined for two chromatographic chemical processes: (i) the transfer of the imidazole derivative from the mobile phase to the stationary phase; and (ii) the imidazole derivative inclusion in surfactant micelles. These thermodynamic data indicate that the main parameter determining chromatographic retention is distribution of the imidazole derivatives to micelles of surfactant while the interaction with the stationary phase play a minor role.

Palladium-catalyzed intramolecular CH arylation of five-membered N-heterocycles

Intramolecular CH arylation of imidazole derivatives is carried out in the presence of a palladium catalyst to form fused heteroaromatic compounds. The reaction of imidazole with 2-iodobenzyl bromide with NaH gives the cyclization precursor in an excellent yield. This then undergoes a palladium-catalyzed intramolecular CH arylation at 100 degrees C to form 5H-imidazo[5,1-a]isoindole in 78% yield.
