Notes:
Michael condensation of benzal-α-acetothienone 1 with ethyl cyanoacetate, cyanoacetamide and acetoacetamide led to the 2(1H)-pyridone derivatives 2 and 3. Compound 2 was condensed with aldehydes, and compound 3 with ethyl acetate, to yield the chalcone analogues 4 and the diketone 7, respectively. By action of phenylhydrazine and hydroxylamine on 4 and 7, the corresponding pyrazole and isoxazole derivatives 5, 6 and 9 were obtained. Reaction of urea and thiourea with 1 gave the dihydropyrimidine derivatives 10 and 11, respectively.
