## Abstract Concave bimacrocyclic imidazolinium ions **8** have been synthesized as precursors for N‐heterocyclic carbenes **9** (NHC) in 13 to 29 % overall yields based on 2‐nitroresorcinol (**1**). As bridgeheads, 2,6‐bis(ω‐alkenyloxy)anilines **3** have been synthesized from **1**. Reaction of *
