The Synthesis and Spectral Properties of Benzofuran Derivative bis-Chalcone

Abstract

Khellin, a natural furanochromone, was isolated from the fruits of Ammi visnaga L. by using a rapid and easy technique. It was then hydrolyzed with 10% KOH to obtain khellinone. From the Claisen-Schmidt condensation of khellinone with terephthalaldehyde, a new benzofuran derivative bis-chalcone was synthesized and its spectroscopic properties were investigated in details.

Keywords

• Khellin, Khellinone, Ammi visnaga L., Claisen Schmidt condensation, Bis-chalcone
