摘要

Oxindoles represent an important heterocyclic scaffold that can be found in many natural products.(1) Several of them show significant bioactivities.(2) In the past decades, a wide range of synthetic methods have been developed, giving access to oxindoles with a variety of functionalities. In particular, palladium-catalyzed cyclization reactions, including Mizoroki–Heck couplings,(3) arylations,(4) and alkylations(5) were shown to be useful. Metal-catalyzed ...
