An expeditious one-pot synthesis of 2,3-diaryl/2-aryl-3-heteroaryl-1,3-thiazolidin-4-ones and 1-aryl-1H,3H-thiazolo[3,4-a]benzimidazoles have been accomplished by condensing hetero/aromatic amine, 2-mercaptoacetic acid, aromatic aldehyde and 1,2-phenylenediamine, 2-mercaptoacetic acid and aromatic aldehyde, respectively, in ionic liquids, viz, 1-butyl-3-methyl-imidazolium tetra fluoroborate and 1-methoxyethyl-3-methylimidazolium trifluoroacetate.

Abstract A series of 1-aryl-1H,3H-thiazolo[3,4-a]benzimidazole derivatives have been synthesized via the three-component reaction of o-phenylenediamine, aromatic aldehydes, and 2-mercaptoacetic acid, catalyzed by magnetite-linked sulfonic acid. This method has the advantages of high yield, extensive adaptability, easy operation, and environmental friendliness. Supporting this acid catalyst on magnetite
