Abstract
Novel heterocyclic dihydropyrimidine-2,4,5(3H)-triones and tetrahydro-2-thioxopyrimidine-4,5-diones were synthesized via three-component reaction between appropriate amines, phenyl isocyanate or phenyl isothiocyanate, and ethyl bromopyruvate in DMF under reflux conditions without using additional bases or catalysts. All the products were obtained in good yield by simple and efficient procedure. The structures of all the synthesized compounds were established from advanced spectroscopic data.
