The Azaallylic Anion as a Synthon for Pd‐Catalyzed Synthesis of Heterocycles: Domino Two‐ and Three‐Component Synthesis of Indoles

Abstract

Piecing it all together with palladium: Two- and three-component cascade processes that are promoted by a multifunctional Pd catalyst lead to indoles in a highly efficient manner (see scheme). The key step is the Pd-catalyzed α-arylation of imines with o-dihalobenzene derivatives.
