Synthesis and Antibacterial Activity of Chalcones and Pyrimidine-2-ones
E-Journal of Chemistry, 2005 Some new chalcones have been prepared by Claisen-schmidt condensation of ketone and different aromatic aldehydes. These chalcones on condensation with urea in presence of acid gave Pyrimidine-2-ones.

The Synthesis and Spectral Properties of Benzofuran Derivative bis-Chalcone
Hittite Journal of Science and Engineering, 2018 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,
