## Abstract Acylation reactions of benzocrown ethers with __N__βphthalimidoβprotected derivatives of Ξ²βalanine and 11βaminoundecanoic acid, respectively, were investigated in acid catalysis by using the Eaton reagent. Deprotection of the obtained compounds by hydrazinolysis afforded derivatives wit
