Studies on Azole Compounds. II. Reaction of Oxazole N-Oxides with Phenylisocyanate to give Imidazole Derivatives

Phosphite-oxazole/imidazole ligands in asymmetric intermolecular Heck reaction.

We describe the application of a new class of ligands--the phosphite-oxazole/imidazole (L1-L5a-g)--in asymmetric intermolecular Pd-catalyzed Heck reactions under thermal and microwave conditions. These ligands combine the advantages of the oxazole/imidazole moiety with those of the phosphite moiety: they are more stable than their oxazoline counterparts, less sensitive to air and other oxidizin...

A spectroscopic study on Calf thymus DNA binding properties of nickel (II) complex with imidazole derivatives of 1,10-phenanthroline ligand

In this study, a nickel (II) complex with 1,10-phenanthroline based ligand, [Ni(FIP)2](OAC)2 (1) with FIP = 2-(Furan-2-yl)-1H-Imidazole[4,5-f][1,10] phenanthroline as ligand was synthesized and characterized by spectroscopic methods and elemental analysis. The interaction of [Ni(FIP)2](OAC)2 (1) with calf-thymus DNA (ct-DNA) was studied by UV-vis absorption, fluorescence spectroscopies and visc...

Antibacterial Activity of Some New Azole Compounds

Hplc Method for Separating Enantiomers of Imidazole Derivatives - Antifungal Compounds.

The aim of this study was to test separation possibility of enantiomers of nine active substances belonging to imidazole derivatives: bifonazole, butoconazole, econazole, enilconazole, fenticonazole, isoconazole, miconazole, sertaconazole and tioconazole. The study was performed using HPLC method and the CHI- RALCEL OJ column (10 gm; 250 x 4.6 mm), the mobile phase flow rate of 0.8 mL/min and d...

Three Component Syntheses of Pyrrolo Imidazole Derivatives in the Presence of N-methyl imidazole, Activated Acetylenes and Phenylsulfonylacetophenone

Because of the significant role in biological processes in living cells and the diverse types of physiological activities, heterocyclic compounds are in focus of intense investigations by academic, industry and applied-oriented chemists. Considerably, ascientific renaissance of heterocycles during the last decades is closely related to the development of multicomponent approaches to their s...
