A novel multicomponent synthesis of ketene dithioacetal rhodanines has been reported by reactions of primary amine, carbon disulfide, ethyl chloroacetate, and alkyl halide in DMF. The catalytic effects of different bases have been investigated and potassiumcarbonate can efficiently catalyze the reaction in moderate to good yields at room temperature.

ABSTRACT The synthesis of rhodanine-derived enaminones has been reported by the reaction of ketene S,S-acetal rhodanine and amine in water under reflux condition. The present methodology includes mild reaction conditions, shorter reaction times, high yield and facileisolation of the desired products by simple filtration. GRAPHICAL ABSTRACT
