KF supported on montmorillonite K10 catalyzed three-component cyclocondensation of aromatic aldehyde, cyclohexan-1,3-dione and malononitrile under ultrasound irradiation and solvent-free condition to give the corresponding 4H-pyrans in high yields. This method provides several advantages such as short time, mild condition and the catalyst can be recycled easily.
