Abstract

In this work, a series of pyridinium-based ionic liquids (PBILs) were synthesized. Pyridinium-based ionic liquids (PBILs) were synthesized through a simple method, which was initially evaluated as catalysts for the synthesis of tetrahydro[b]benzopyran derivatives via a one-pot three-component reaction involving aldehydes, malononitrile, and dimedone. The PBILs perform well in this condensation reaction, especially 1-methylpyridin-1-ium dimethyl phosphate (MPDMP). The advantages of this procedure are good yields, short reaction time, simplicity of implementation, and inexpensive starting materials.

期刊介绍： Current Organocatalysis is an international peer-reviewed journal that publishes significant research in all areas of organocatalysis. The journal covers organo homogeneous/heterogeneous catalysis, innovative mechanistic studies and kinetics of organocatalytic processes focusing on practical, theoretical and computational aspects. It also includes potential applications of organocatalysts in the fields of drug discovery, synthesis of novel molecules, synthetic method development, green chemistry and chemoenzymatic reactions. This journal also accepts papers on methods, reagents, and mechanism of a synthetic process and technology pertaining to chemistry. Moreover, this journal features full-length/mini review articles within organocatalysis and synthetic chemistry. It is the premier source of organocatalysis and synthetic methods related information for chemists, biologists and engineers pursuing research in industry and academia.
