A facile and efficient one-pot procedure for the synthesis of 5-imino-3,5-dihydro-2H-chromeno[3,4-c]pyridin-2-one derivatives via a four-component reaction of salicylaldehyde, malononitrile, ethyl cyanoacetate and hydrazine hydrate under mild conditions in excellent yield is described. The structures of fused molecules have been unambiguously confirmed by their spectroscopic techniques as well as by single crystal X-ray analysis.
