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.

高效、可重复使用的官能化吡啶鎓盐作为催化剂，用于简单且经济高效地制备四氢[b]苯并吡喃衍生物

本文合成了一系列吡啶基离子液体。通过一种简单的方法合成了吡啶基离子液体（PBILs），该方法最初被评估为通过涉及醛、丙二腈和二酮的一锅三组分反应合成四氢[b]苯并吡喃衍生物的催化剂。PBILs在该缩合反应中表现良好，尤其是1-甲基吡啶-1-二甲基磷酸铵（MPDMP）。该方法的优点是产率高、反应时间短、实施简单和原料便宜。

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.
