Abstract: A rapid, solvent-free and environmentally friendly Knoevenagel condensation reaction of 4-oxo-(4<i style="">H</i>)-1-benzopyran-3-carbaldehyde <b style="">1</b> with Meldrum’s acid <b style="">2</b> has been carried out under microwave irradiation. The structures of condensed products <b style="">3a-g</b> have been characterized on the basis of IR and <sup>1</sup>H NMR spectral data.
