finyl imine affords 5‐ or 6‐membered cyclic compounds containing exocyclic 1,3‐diene moieties in a stereoselective manner. The reaction proceeds through β‐hydride elimination of a 7‐membered azarhodacycle intermediate, which is generated from three unsaturated bonds (i.e., alkene, alkyne, and CN bonds) and an Rh(I) complex. The resultant cyclic compounds could be reacted with various dienophiles to
