Full TextAbstract
A facile and efficient greener synthesis of a novel four-fused ring heterocyclic system via three-component reactions of [1,3,4]thiadiazolo[3,2-a]pyrimidin-5-one, aromatic aldehyde, and 1,3-cyclohexanediones, in the presence of 1-(4-sulfonic acid) butyl-3-methylimidazolium hydrogen sulfate, has been presented. The synthesized compounds were characterized by mass spectrometry, IR, 1H-NMR, 13C-NMR, and elemental analysis. The remarkable features of this method are using acidic ionic liquid catalyst, green solvent media, short reaction time, good yields, and simple purification techniques.
