Abstract
A method for the synthesis of aza-crown compounds by the intramolecular cyclization of ω-amino acids with subsequent reduction of the lactam to a macrocyclic amine was developed. 1,8-Diazacyclotetradecane and 1,8-dioxa-4,11-diazacyclotetradecane were synthesized in preparative yields. The structural assignments were made using the IR, 1H and 13C NMR, and mass spectra.
