Abstract

Substituted 4H-chromenes were easily prepared by reaction of salicylaldehydes and ethylcyanoacetate in solvent free conditions using potassium exchanged layered zirconium phosphate as catalyst. This method could be employed in the preparation of a wide variety of 4H-chromene models under extremely mild conditions.
