Abstract
AbstractThe usual way to synthesize spiroindolinones is the application of isatin derivatives. Here, we report the first Pd‐catalyzed Buchwald–Hartwig addition–elimination strategy for the formation of the spiroindolinone–isoindolinone architecture. The application of the Ugi‐4‐component reaction (Ugi‐4CR) allows the facile introduction of diversity and increases the practicality of this protocol.
