## Abstract Acylation reactions of benzocrown ethers with __N__‐phthalimido‐protected derivatives of β‐alanine and 11‐aminoundecanoic acid, respectively, were investigated in acid catalysis by using the Eaton reagent. Deprotection of the obtained compounds by hydrazinolysis afforded derivatives wit
