A new series of chalcone derivatives containing a benzothiophene moiety were synthesized via a base-catalyzed Claisen–Schmidt condensation reaction. The synthetic strategy involved the condensation of 2-methyl-1-benzothiophene-3-carbaldehyde with various substituted acetophenones in the presence of sodium hydroxide using methanol as a solvent. The reaction proceeded smoothly to afford the corresponding (E)-1-(substituted phenyl)-3-(2-methylbenzothiophen-3-yl)prop-2-en-1-one derivatives in good to excellent yields. Different electron-withdrawing and electron-donating substituents such as Cl, F, OCH₃, CH₃, and H on the aromatic ring were explored to study their influence on the reaction outcome. The structures of the synthesized compounds were confirmed by spectral techniques including FT-IR, ¹H NMR, ¹³C NMR, and mass spectrometry. The presence of the α,β-unsaturated carbonyl system along with the benzothiophene nucleus makes these compounds promising scaffolds for further biological evaluation.
