One‐Pot/Four‐Step/Palladium‐Catalyzed Synthesis of Indole Derivatives: The Combination of Heterogeneous and Homogeneous Systems

Abstract One‐pot, four‐step syntheses of indoles using both solid‐supported heterogeneous and homogeneous palladium catalysts and reagents were carried out. Such a combination of these two‐phase catalysts and reagents causes a dramatic increase in yield, and it is a simple process. The presented methodology is effective for four‐step reactions to provide various functionalized indoles.
