## Abstract A novel Lewis acid‐catalyzed [3+4] annulation of 2‐(heteroaryl)cyclopropane‐1,1‐dicarboxylates with cyclopentadiene is reported. This reaction proceeds __via__ an electrophilic attack of the Lewis acid‐activated donor‐acceptor cyclopropane onto cyclopentadiene followed by Friedel–Crafts
