Palladium-Catalyzed Synthesis of Indolines from Aroyloxycarbamates through a Tandem Decarboxylative Amination/Heck/Annulation Reaction

A novel synthesis of functionalized indolines via a Pd-catalyzed tandem decarboxylative amination/Heck/annulation reaction has been developed. This process features operational simplicity, mild conditions, and the use of a readily available and environmentally friendly starting material, namely carboxylic acid. Furthermore, the reaction shows good functional group tolerance and chemical selectivity. (Figure presented.).
