A mild and efficient protocol for the synthesis of 2-amino-5-arylidene-1,3- thiazol-4(5H)-ones is reported by three component reaction of aldehydes, rhodanine and secondary amines in the presence of magnesium oxide nanoparticles as heterogeneous nanocatalyst in good yields and short reaction times.

Piperidine, morpholine and benzylamine react with 5-arylmethylene-4-oxo-2-thioxothiazolidines (I) to give the corresponding piperidine (IIa-d), morpholine (IIe-f) and benzylamine (IIg) salts which on treatment with ethanol undergo decomposition to give the respective 2-piperidino- and 2-morpholino-4-oxo-2-thiazolines (III), and 2-benzylimino-4-oxothiazolidine (IVa).However, decomposition of IIa-d in the presence of an equimolar amount of morpholine gives mixtures of 2-piperidino- and 2-morpholino-4-oxo-2-thiazolines (III).Furthermore, decomposition of IIe, c and d inthe presence of an excess of a primary amine affords exclusively the respective 2-substituted-imino-4-oxo-thiazolidines (IV).Cleavage of 5-arylmethylene-3-methyl-4-oxo-2-thioxothiazolidines (Va-b and e-g) with excess of piperidine affords 1-(N-methylthiocarbamyl)piperidine (VI).The structures of II, III, IV and VI are based on analytical and spectral data.
