A series of pyrano[3,2-c]pyridine derivatives were synthesized via reactions of 3,5-dibenzylidene-piperidin-4-one and malononitrile in N,N-dimethylformamide undermicrowave irradiation. It is a simple, efficient, and promising synthetic method to construct pyrano[3,2-c]pyridine skeleton. J. Heterocyclic Chem., (2009).
