with a catalytic amount of TpRuCl(PPh3)2 resulted in the construction of indole scaffolds known as privileged structure motifs. This reaction involved a cascade of 1,2‐rearrangement and cyclization carrying out C−C bond formationvia a rutheniumvinylidene intermediate, as revealed by a deuterium‐labeling experiments. Furthermore, the transformation of multi‐functionalized ynamide, derived from a practical
