摘要：

In this study, an acidic nicotine-based ionic liquid supported on magnetic nanoparticles ([NicTC]HSO4@MNPs) was synthesized and characterized by different techniques. The activity of this catalyst was evaluated in a multi-component reaction of 2-aminobenzothiazole, aldehydes/dialdehydes and beta-ketoesters/1,3-diketones to afford a series of novel mono- and bis-4H-pyrimido[2,1-b]benzothiazole derivatives. In addition, mild reaction conditions, high yields, excellent selectivity as well as easy recovery and reusability of the catalyst, make this method an economic and environmentally-benign process.
