Abstract: The tetrahydrofolate coenzyme is the methyl source of the methylation for many materials (including the DNA and RNA) in the living body to transfer one carbon unit for the biosynthesis and metabolism. On the basis of the one-carbon unit transfer reaction of tetrahydrofolate coenzymes, six cyclohexyl ketone compounds were synthesized successfully with benzimidazolium salt as the tetrahydrofolate coenzyme model at formic acid oxidation level and Grignard reagent as a nucleophile to which one carbon unit was transferred via addition-hydrolysis reaction. Their structures were characterized by elemental analysis, 1H NMR, IR and MS spectra. A novel method for the convenient biomimetic synthesis of cyclohexyl ketone compounds was provi-ded. The reaction mechanism and the effects of reaction conditions on the yield were investigated.

Key words: Cyclohexyl ketone compound, Tertrahydrofolate coenzyme model, Benzimidazolium salt, Grignard reagent, Biomimetic synthesis
