efficient routes to benzothieno[2′,3′:4,5]pyrrolo[1,2‐f]phenanthridines have been developed. Alkynylated benzothiophenes reacted with various anilines to the target compounds in a domino reaction consisting of a C−N coupling‐, hydroamination‐ followed by a final, ring‐closing C−H arylation step. Products were isolated in moderate to good yields.
