## Abstract The formal [3+2] dipolar cycloaddition (or annulation) of donor‐acceptor cyclopropanoate esters with pyridines and 5‐nitroquinoline is reported. Electron‐deficient pyridine dipolarophiles (R=CN, CO~2~Et, COMe) participate in the annulation whereas electron rich species do not. The produ
