Diels-Alder reactions of 1-unsubstituted 2 (1H)-pyridones having two electron-withdrawing groups on the ring with a diene were carried out and the reactions gave expected Diels-Alder adducts. The yields of adducts were well correlated with the corresponding stabilization energies (ΔE) between a diene and dienophiles calculated using the semiempirical molecular orbital method.
