LEYVA-RAMOS, Socorro; LEYVA, Elisa; CARDOSO-ORTIZ, Jaime  y  HERNANDEZ-LOPEZ, Hiram. Microwave-assisted synthesis of ethyl 7-chloro-4-oxo-l,4-dihydro-1,8-naphthyridine-3-carboxylate by the Grohe-Heitzer reaction. J. Mex. Chem. Soc [online]. 2017, vol.61, n.1, pp.50-53. ISSN 1870-249X.

A simple and efficient two-step method was implemented for the synthesis of ethyl 7-chloro-4-oxo-1,4-dihydro-1,8-naphthyridine-3-carboxylate. Comparing with the reported Grohe-Heitzer reaction, the time and the reaction steps have been reduced using microwave irradiation. This compound is an important intermediate for the preparation of naphthyridone derivatives which have received significant attention due to their broad spectrum of biological activity.

Palabras llave : Grohe-Heitzer reaction; 1,8-naphtyridone; microwave irradiation; tautomeric equilibrium.
