A facile approach has been developed for the synthesis of dihydrocoumarin derivatives through the reaction of phenols and cinnamoyl chloride in the presence of ecofriendly solid-acid catalyst montmorillonite K-10 via a tandem esterification-Friedel-Crafts alkylation process under microwave irradiation. The catalyst could be easily recovered and recycled.
