چکیده	A simple, green and efficient protocol for the one-pot four-component synthesis of pyrano[2,3-c]pyrazole derivatives produced from reaction between aryl aldehydes, ethyl acetoacetate, malononitrile and hydrazine hydrate in the presence of nano magnetic piperidinium benzene-1,3-disulfonate was synthesized in water at 60 °C. The Fe3O4@SiO2 nanoparticle-supported IL was designed and synthesized. The present process offers advantages such as clean reaction, short reaction time, good to excellent yield, easy purification and easy recoverable catalyst. Copyright © 2017 John Wiley & Sons, Ltd.
