A facile clean synthesis of pyrido [2,3-d] pyrimidine and their derivatives in ionic liquids

Yadav, Ashok K.,Gupta, Manisha

, p. 1247 - 1254 (2015/01/08)

Chalcone on reaction with malononitrile in ionic liquid affords 2-amino-3-cyano-4,6-disubstituted pyridines in excellent yield. The pyridine derivatives are used as precursor for the synthesis of 5,7-disubstituted pyrido[2,3-d] pyrimidine-4(3 H)-one 4a-d
