Abstract

An efficient and diastereoselective synthetic method for preparing (E)-3-styrylchromones has been developed by the reaction of chromone-3-carboxaldehyde with phenylacetic acids in the presence of potassium tert-butoxide under classical heating conditions or microwave irradiation. The Knoevenagel-type reaction followed by a decarboxylation was faster under microwave conditions.
