A green protocol for the synthesis of unsubstituted imidazoles has been demonstrated herein. The reaction is realized using commercially available lipase enzyme, porcine pancreas lipase (PPL) in water. The reaction conditions are selective and mild which helped to tolerate a wide variety of functional groups to give the desired products in good chemical yields. (Figure presented.).

Conditions of aromatization of 2-(2-hetaryl)imidazolines and their analogs with various dehydrogenating agents were examined. A new catalytic system, Pd/C-diphenyl oxide, was studied, and the optimal catalyst:imidazoline ratio ensuring formation of 2-substituted imidazoles in high yield was found.

A simple, convenient and high-yielding one-pot method for the synthesis of 2-heterocycle-substituted imidazoles from the corresponding nitriles has been developed. The procedure is easily scaleable and the workup does not involve chromatography. This synthesis is also applicable to the preparation of imidazoles with electron-poor aryl substituents.
An efficient synthesis of 2-arylimidazoles by oxidation of 2-arylimidazolines using activated carbon-O2 system and its application to palladium-catalyzed Mizoroki-Heck reaction

Oxidative conversion of 2-substituted imidazoline (dihydroimidazole) to the corresponding imidazole was achieved by an activated carbon-O2 system. Also, the 2-arylimidazolines and 2-arylimidazoles have been found to work as simple ligands in the palladium-catalyzed Mizoroki-Heck reaction.
An efficient preparation of 2-imidazolines and imidazoles from aldehydes with molecular iodine and (diacetoxyiodo)benzene
Ishihara, Midori,Togo, Hideo
, p. 227 - 230 (2007/10/03)
2-Imidazolines were easily prepared in quite good yields from the reaction of aldehydes and ethylenediamine with molecular iodine in the presence of potassium carbonate. Moreover, 2-imidazolines obtained were smoothly oxidized to the corresponding imidazoles in good yields using (diacetoxyiodo)benzene at room temperature. Georg Thieme Verlag Stuttgart.
INVESTIGATIONS OF 2-SUBSTITUTED IMIDAZOLES. 2. SYNTHESIS AND ELECTROPHILIC SUBSTITUTION OF 1-METHYL-2-(THIENYL-2)IMIDAZOLE. A CONVENIENT METHOD OF METHYLATION OF 2-R-IMIDAZOLES

We have synthesized 2-(thienyl-2)imidazole and its N-methyl derivative.The latter product was obtained by nitration, bromination, acylation, and formylation, occurring as a rule on the thiophene ring.A general method for methylating 2-R-imidazoles with methyl iodide KOH-dimethoxy ethane is proposed.
