8-oxabicyclo[3.2.1]octadiene derivatives. It has been proposed that this involves an initial Diels−Alder reaction followed by rearrangement of the primary adduct. We have, for the first time, isolated a primary adduct and established through X-ray crystallographic analysis that the adduct is the product of an exo-selectiveaddition. Kinetic studies suggest the intermediacy of charged intermediates during the rearrangement
