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.
