Abstract

A series of new 8-aryl-7,8-dihydro[1,3]dioxolo[4,5-g]chromen-6-ones were synthesized via a three-component reaction of 3,4-methylenedioxyphenol, aromatic aldehydes and Meldrum’s acid in the presence of CeCl₃·7H₂O under solvent-free conditions. The method provided several advantages such as easy work-up, high yields and environmentally benign procedure.

Keywords: [1,3]Dioxolo[4,5-g]chromen-6-one; Meldrum’s acid; CeCl₃·7H₂O; Solvent-free.
