One-pot Synthesis of 2,4,5-trisubstituted Imidazoles Catalyzed by Lipase

A simple and efficient protocol of synthesizing 2,4,5-trisubstituted imidazoles has been developed using lipase as a novel catalyst under mild conditions. A series of imidazole derivatives were synthesized with good yields. The probable enzymatic mechanism was proposed. This method expands the catalytic scope of lipase and provides a novel method to prepare imidazole derivatives.

Electrochemical and molecular dynamics simulation studies on the corrosion inhibition of aluminum in molar hydrochloric acid using some imidazole derivatives

The corrosion inhibition and adsorption characteristics of three selected imidazole derivatives namely, 2-amino-4,5-imidazoledicarbonitril (AID), 5-amino-4-imidazolecarboxamide (AIC) and imidazole (IM) on aluminum in 1.0 M HCl was investigated at 25 A degrees C. Measurements were carried out under various experimental conditions using chemical (weight loss), and electrochemical (Tafel polarization and impedance) methods. Molecular dynamics (MD) method and density functional theory were also applied here for theoretical study. Results obtained showed that inhibition efficiency of these compounds increases with increase in their concentrations due to the formation of a surface film on the aluminum surface. Adsorption energy as well as hydrogen bond length calculations showed that AID was the best corrosion inhibitor among the tested imidazole derivatives. Polarization measurements reveal that the selected imidazole derivatives function mainly as cathodic-type inhibitors. Physisorption, followed by chemisorption was proposed as the mechanism for the inhibition process. Adsorption via H-bond formation was also considered here. Results obtained from theoretical study were found to confirm experimental findings.

Highly substituted imidazole derivatives from a new four-component synthesis employing methoxyallene

A novel four-component reaction of alkoxyallenes with imines, iodine, and nitriles provided highly substituted imidazole derivatives in high overall yields. The simple three step protocol, exemplified by the reaction of methoxyallene (1) with imine 2, acetonitrile, and iodine leading to iodoethenyl imidazole 6 is presented with full experimental detail. Imidazole 6 could be further functionalized by palladium-catalyzed couplings yet offering an entry into diversity-oriented synthesis.

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 38668-46-1. Product Details of 38668-46-1.

QSAR study for classes with a broad range of biological activity using electronegativity descriptors for OMO-UMO quantum states. Clotrimazole imidazole derivatives with antiftingal activity

The class of clotrimazole imidazole derivatives having a broad spectrum of antimycotic activity has been studied using fingerprint descriptors based on electronegativity, of the occupied molecular orbitals (OMO) and unoccupied molecular orbitals (UMO). The Hansch equation Kd = a(0) + a(I)X(I), where X, = OMO / UMO electronegativity allows us to identify the nature of the atoms involved in ligand (drug)-receptor interactions, as well as the nature of those interactions.

Electrosynthesis of an imidazole derivative and its application as a bifunctional electrocatalyst for simultaneous determination of ascorbic acid, adrenaline, acetaminophen, and tryptophan at a multi-wall carbon nanotubes modified electrode surface

In this research, the electrosynthesis of 4-(1H-benzofdlimidazol-2-ylthio)-5-methylbenze-1,2-diol (as an imidazole derivative) is reported. An imidazole derivative multi-wall carbon nanotube modified glassy carbon electrode (IMWCNT-GCE) was constructed and used as an excellent bifunctional electrocatalyst for oxidation of ascorbic acid (AA) and adrenaline (AD). Cyclic voltammetry was used to calculate the surface electron transfer rate constant, k(s), and the electron transfer coefficient, alpha, for the electron transfer between MWCNT-GCE and the electrodeposited imidazole derivative. The kinetic parameters such as the electron transfer coefficient, alpha, and the heterogeneous rate constant, k’, for the oxidation of AA and AD at the IMWCNT-GCE surface were estimated. The modified electrode was found quite effective for the simultaneous determination of AA, AD, acetaminophen (AC), and tryptophan (Trp) in a mixture solution. The detection limits of AA and AD were calculated as 0.961 mu M and 0.38 mu M, respectively. Finally, IMWCNT-GCE was satisfactorily used for the determination of AA, AD, and AC in pharmaceutical samples. (C) 2012 Elsevier B.V. All rights reserved.
