reacted with a series of twelve electron-poor and electron-rich dienophiles to give, in some cases, the corresponding Diels−Alder adducts. Clear differences in the roles played by the two frontierorbitalinteractions emerged. It was demonstrated that in the case of normal Diels−Alder cycloadditions, the FMO theory could predict the relative reactivities between dienophiles, while in the case of inverse-electron
