Résumé

Aurones are natural bioactive dyes found in plants, and many of them are biologically active. We reported herein that α,β-dicarbonyl compounds condense with 3-coumarones without a solvent under microwave irradiation with clay as a catalyst. Novel acylaurones were obtained in good yields; the more stable E-isomer was formed stereoselectively.
