چکیده
a highly practical and efficient preparation of pyrano[3,2-c]pyridone and pyrano[3,2-c]quinoline derivatives was developed via an ionic liquid mediated and promoted multi-component reaction of malononitrile, aldehyde, and 4-hydroxyquinolin-2(1h)-one or 4-hydroxy-6-methylpyridin-2(1h)-one. the combinatorial syntheses were achieved for the first time without applying extra activation energy at ambient temperature while making use of [bmim]cl as a catalyst solvent.
