The effect of Lewis acid catalysts, TiCl₄ and Et₂AlCl on the intramolecular cycloaddition Diels- Alder (IMDA) reaction of triene-amide have been studied theoretically using the DFT (Density Functional Theory) at the 6-31G(d,p) level of theory. The results obtained using the polar model of Domingo, electrophilicity, nucleophilicity indices and thermochemistry computations, demonstrate that these catalysts are coordinated with more nucleophilic atoms of diene fragment (nitrogen and oxygen of amide group). These catalysts affect negatively the feasibility of the reaction as well as the physico-chemical parameters of the IMDA reaction of triene-amide.
