摘要

Oxindoles that incorporate a quaternary stereogenic center at C3 are attractive targets in organic synthesis because of their significant biological activities as well as wide-ranging utility as synthetic intermediates for alkaloids, drug candidates, and clinical pharmaceuticals.[1] Therefore, a number of synthetic methods have been developed in pursuit of this structure, including intermolecular alkylations,[2] palladium-catalyzed ...
