Clay Catalysis: Solventless Condensation of Benzofuran-3(<i>2H</i>)-One with α,β-Dicarbonyl Compounds under Microwave Irradiation: Synthesis of New Acyl-Aurones
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 st...

| Summary: | 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 <i>E</i>-isomer was formed stereoselectively. |
