In this research, we have developed an efficient three‐component reaction for the synthesis of pyrano[3,2‐ c ]pyridine derivatives from the reaction of aromatic aldehydes, tert ‐butyl 2,4‐dioxopiperidine‐1‐carboxylate, and N ‐methyl‐1‐(methylthio)‐2‐nitroethylen‐1‐amine in [BMIM]BF 4 medium. The advantages of this method were readily available starting materials, simple reaction conditions, and satisfactory yields.
