摘要：Palladium-catalyzed asymmetric formal [3+2] cycloaddition. of vinyl cyclopropanes and beta,gamma-unsaturated alpha-keto esters proceeded smoothly in the presence of chiral imidazoline-phosphine ligands to give the corresponding highly functionalized cyclopentanes in good yields along with high diastereo- and enantioselectivities under mild conditions.
