A green and efficient method was described for one pot synthesis of 3-pyranyl indole derivatives by reaction of 3-cyano acetyl indole, aromatic aldehydes and malanonitrile in an aqueous media under reflux by using [Bmim]BF4 as a green catalyst. Simple and easy work process, use of green catalyst, green solvent, short reaction time and excellent yields of the products are the advantages of this method.

3-cyano acetyl indole, aromatic aldehydes, malanonitrile, [Bmim]BF4.
