A novel approach for the synthesis of nicotinate derivatives has been developed by using Lewis acidic ionic liquid[Bmim]ZnBr3, which acts as dual solvent-catalyst in promoting the tandem reaction of enaminoester and allenic ketones. In the reaction process, no catalysts or other organic solvents are used, and[Bmim]ZnBr3 can be readily reused for three times without noticeable decrease in the catalytic activity after simple treatment. Furthermore, our method offers several advantages such as short reaction times, simple work-up procedure, environment-friendly solvent and good yields. The current methodology could also be conveniently applied to the synthesis of natural products and complex therapeutic agents occurring niacin frameworks.

Key words: ionic liquid, enaminoester, allenic ketone, nicotinate
