A reactive diene, ethyl 2-methylene-4-(pent-3-oxy)but-2-enoate, bearing electron-withdrawing carboxy and electron-donating pentoxy substituents is prepared and trapped in situ by a variety of dienophiles to form [4+2] cycloaddition products. Diels–Alder reaction of this diene with fumarate esters gives multiply substituted cyclohexenes that are useful for building the scaffold of oseltamivir.
