Synthesis of Fluorinated 2-Benzylbenzimidazoles Under Superelectrophilic Activation Conditions and Investigation of Their Antimicrobial Properties
Fluorinated 2-hydroxymethylbenzimidazoles reacted with benzene in the Brønsted superacid CF3SO3H at 140C in 2.5 h to afford the corresponding 2-benzylbenzimidazoles in yields of 61–73%. According to experimental NMR studies and theoretical DFT calculations, the key reactive electrophiles in this reaction are N-protonated O-protosolvated forms of starting benzimidazoles. Antimicrobial activity against Escherichia coli and Staphylococcus aureus bacteria, as well as yeast-like fungi Candida albicans was evaluated for the starting and target fluorinated benzimidazoles. These compounds exhibited the highest biological activity in relation to Candida albicans fungi.
期刊介绍:
Russian Journal of General Chemistry is a journal that covers many problems that are of general interest to the whole community of chemists. The journal is the successor to Russia’s first chemical journal, Zhurnal Russkogo Khimicheskogo Obshchestva (Journal of the Russian Chemical Society ) founded in 1869 to cover all aspects of chemistry. Now the journal is focused on the interdisciplinary areas of chemistry (organometallics, organometalloids, organoinorganic complexes, mechanochemistry, nanochemistry, etc.), new achievements and long-term results in the field. The journal publishes reviews, current scientific papers, letters to the editor, and discussion papers.
