Resumen

KHALFALLAH, Ali y KHADDACHI, Mohamed T.. Synthesis and characterization of ethyl 2-methyl-7-oxo-7H-isoxazolo[2,3-α ]pyrimidine-6-carboxylate derivatives. S.Afr.j.chem. (Online) [online]. 2010, vol.63, pp.62-64. ISSN 1996-840X.

Reactions of 5-methylisoxazol-3-amine with diethyl ethoxymethylenemalonate derivatives are described. By this method ethyl 2-methyl-7-oxo-7H-isoxazolo[2,3-a]pyrimidine-6-carboxylate derivatives were prepared and characterized.

Palabras clave : Isoxazolo[2,3-a]pyrimidine-6-carboxylate; heterocyclic; aminoisoxazole.
