divinyl alkoxyacetates (such as 7a) undergo a Eu(fod)3-catalyzed regiospecific allylic rearrangement to form C5-substituted (E)-2-ethoxy-1,3-dienes at room temperature. When the rearrangement of 7a was carried out in the presence of maleic anhydride, a tandem allylic rearrangement and Diels–Alderreaction occurred to give the adduct 11. Reactions of other dienophiles in this tandem procedure were examined
