Palladium-catalyzed asymmetricformal [3+2] cycloaddition of vinyl cyclopropanes and β,γ-unsaturated α-keto esters proceeded smoothly in the presence of chiral imidazoline–phosphine ligands to give the corresponding highlyfunctionalized cyclopentanes in good yields along with high diastereo- and enantioselectivities under mild conditions.

Highly efficient DABCO-catalyzed [4 + 2] cycloaddition of β,γ-unsaturatedα-ketophosphonates or β,γ-unsaturated α-ketoesters with allenicesters gives the corresponding highlyfunctionalized tetrahydropyran and dihydropyran derivatives in good to excellent yields and moderate to good regioselectivities under mild conditions.
