The present work focuses on the synthesis and characterization of novel chalcone-based quinoline derivatives with potential pharmacological significance. Chalcones are important bioactive compounds known for their diverse biological activities such as antioxidant, antimicrobial, and anticancer properties. In this study, N-methyl aniline was first subjected to acetylation using acetic anhydride to form an intermediate amide. This was further cyclized using DMF and POCl₃ via the Vilsmeier–Haack reaction to obtain a quinoline aldehyde derivative. The synthesized aldehyde was then reacted with substituted acetophenones through Claisen–Schmidt condensation in the presence of a base catalyst to yield the desired chalcone derivatives. The synthesized compounds were characterized using spectroscopic techniques such as ¹H NMR, IR, and LC-MS to confirm their structure and purity. The spectral data supported the formation of the α, β-unsaturated carbonyl system characteristic of chalcones. Based on literature studies, these compounds are expected to exhibit significant pharmacological activities. Further biological evaluation of the synthesized compounds is under progress and will be reported in future studies.
