## Abstract Crown ethers containing a thiazole subcyclic unit are prepared from the reactions of 1,3‐bis[2(4‐hydroxymethylthiazoyl)]benzene with di‐__p__‐tosylates of corresponding di, tri, tetra, pentaethylene glycols in the presence of potassium hydride. However, if the cavity size in the ring sy
