NARENDER, ATMAKURI; LAXMINARAYANA, E  y  THIRUMALA CHARY, M. A NOVEL SYNTHESIS OF SUBSTITUTED 4-HYDROXY- 1,8-NAPHTHYRIDINES. J. Chil. Chem. Soc. [online]. 2009, vol.54, n.4, pp. 473-474. ISSN 0717-9707.  http://dx.doi.org/10.4067/S0717-97072009000400033.

Michael addition of 2-aminopyridines with methylpropiolate to afforded the addition compound 1^a-g, which on further cyclisation at higher temperature in dowtherm-A to yield cyclised product 2 ^a-g, with respective yields depends on the nature of the substituents.

Palabras llave : Propionoic acid methyl ester; 2-aminopyridine and 3-(Pyridin-2-ylamino)-acrylic acid methyl ester.
