| Abstract: | An efficient and rapid four component reaction of aldehydes, malanonitrile, β‐ketoesters and hydrazine hydrate (or phenyl hydrazine) in environmentally benign room temperature ionic liquid choline chloride‐urea has been developed for the synthesis of substituted 4H‐pyrano2,3‐c]pyrazoles. |
