We exploited the utilization of 2‐methyl‐2‐phenyl‐1,3‐oxathiolan‐5‐one ( 1 ) that acts as activated thioglycolic acid as mercaptoacetyl transfer agent to build new pyridinonethiol derivatives via multicomponent domino reactions of 1 with different acyclic or cyclic α , β ‐unsaturated carbonyl compounds and aniline using CeCl 3 ∙7H 2 O/KI as Lewis acid catalyst. Furthermore, the new synthesized compounds were biologically evaluated for antitumor efficiency. The geometries and normal modes of vibrations obtained from calculations are in good agreement with the experimentally observed data.
