A simple, efficient, environment-friendly and high yielding procedure is developed for the Knoevenagel condensation and the combination of Knoevenagel/ Michael addition reaction of various 1, 3-dicarbonyls and aryl aldehydes in an aqueous surfactant medium. The reaction can be dramatically improved under microwave-irradiation.
