Synthesis and structure elucidation of opticallyactive tri-, tetra-, and penta-azamacrocycles having 4-methoxyphenyl pendants are described. Regioselective ring opening of a nosylaziridine with secondary benzyl amines was repeatedly performed to afford the cyclization precursors. Intramolecular N-alkylation of N-(ω-haloalkyl) nosylamide provided tri-, tetra-, and penta-azamacrocycles. On the basis
