Abstract
- A highly efficient palladium(0)-catalyzed asymmetric [3+2] cycloaddition using 3-diazooxindoles serving as dipolarophiles affords functionalized pyrazolidine derivatives in an atom-economical way. In addition, by trapping the pyrazolidine derivatives with maleimides, the corresponding spiropyrazolidine oxindoles containing multiple stereogenic centers have been obtained in high yields along with moderate to good levels of diastereoselectivity and enantioselectivity under mild conditions. Thus, a novel three-component one-pot tandem reaction has been developed. [ABSTRACT FROM AUTHOR]
