A novel and efficient domino annulation for the construction of unrevealed polycyclic 3, 4‐fused indoles involving rhodium(III)‐catalyzed alkyne insertion followed by aza ‐Michael addition is presented. A variety of N ‐(pivaloyloxy)arylamides and N ‐(pivaloyloxy)‐1 H ‐indole‐1‐carboxamides were utilized in this annulation with 4‐alkynyl‐3‐alkenyl indoles.
