摘要

A convenient and efficient synthesis of enantiomerically pure 12-, 14-, and 16-membered tetraazamacrocyclic ligands, able to form complexes with transition metal cations, is discussed. Linear α, ω-aminoesters, prepared from l-proline, undergo intramolecular aminolysis to afford the corresponding macrocyclic amides in good yields.
