Abstract

AbstractA Pd‐catalyzed coupling reaction fromo‐alkynylanilines ando‐(2,2‐dibromovinyl)anilines for the synthesis of 2,3′‐bisindoles is developed. In which,o‐ethynylaniline was used as 3‐functionalized indole precursor ando‐(2,2‐dibromovinyl)aniline was used as 2‐functionalized indole precursor. This protocol exhibits high efficiency, good functional group tolerance and scalability from easily accessible starting materials.
