The reaction of a symmetrical allylic dicarbonate or diacetate with a variety of β-keto esters in the presence of a palladium catalyst gave 2-substituted 5-vinyl-4,5-dihydrofuran-3-carboxylates, 4,6a-dihydro-3aH-cyclopenta[b]furan-3-carboxylates, and 3a,4,5,7a-tetrahydrobenzofuran-3-carboxylates in moderate to good yields.
