    Quantum chemical calculations are used to investigate the experimentally measured reactivities of cyclic dienes and cycloalkenones in the Diels–Alder reaction. The interaction energies (red) are nearly constant; differences arise in changes in distortion energies of both dienophile (blue) and diene (green; see picture, Ea=activation energy; values in kcal mol−1).
