A practical approach for the synthesis of oxindole and isatin derivatives by Pd-catalyzed intramolecular amination

Abstract

Oxindole/isatin-N-acetamide derivatives are a class of important pharmacologically active compounds. Herein, we report a practical protocol for the synthesis of such derivatives based on palladium-catalyzed intramolecular amination. Various functional groups are tolerated, and the corresponding products are obtained in moderate to good yields, highlighting the potential synthetic utility of this method.
