## Abstract A six‐step synthetic route to four lipophilic crown ethers with intraannular carboxylic acid groups and ring sizes of 15‐crown‐4, 18‐crown‐5, 21‐crown‐6 and 24‐crown‐7 is described. Eight new polyether compounds that bear inward‐facing bromo and formate ester substituents are prepared a
