An expedient one-pot synthesis of highly substituted imidazoles using supported ionic liquid-like phase (SILLP) as a green and efficient catalyst and evaluation of their anti-microbial activity
An efficient method for the synthesis of imidazole derivatives by a three-component condensation of benzil or 9,10-phenanthrenequinone, aldehydes and ammonium acetate using supported ionic liquid-like phase (SILLP) catalyst underultrasonicirradiation or classical heating conditions is reported. The present methodology offers several advantages, such as excellent yields, simple procedures, short reaction

practical and modular assembly of diverse ring-fused phenanthroimidazoles, including an unusual rearrangement product using aryl-alkyl asymmetric alkyne and a thiophenefused product which could serve as a Fe3+ fluorescent probe. The feasibility of the one-pot synthesis and ruthenium(II)-catalyzed versions of this reaction was also verified.
An efficient one-pot approach for the preparation of 2,4,5-trisubstituted phenanthroimidazole derivatives is described. The three-component reaction between 9,10-phenanthraquinone, benzaldehyde derivatives, and ammonium acetate proceeds in the presence of SBA-Pr-SO3H as a nanoporous solid acid catalyst in short reaction times and good to excellent yields.
