Abstract A simple, rapid, and highly efficient method has been developed for the Michael addition of activemethylenecompounds to chalcones using potassium carbonate and water under microwave irradiation. The method is totally exempt of organic solvents, and pure products were obtained in good to excellent yields. This method can be used for the parallel synthesis and further scale‐up to 50 mmol of
