摘要：

Seven new per(N-formyl)polyaza-crown macrocycles 1-7 containing 14 to 21 ring members have been synthesized in yields of over 40% via the cyclization reaction of the appropriate per(N-formyl)polyamine 11-13 with the appropriate ditosylate, dibromide or diiodide. Three of the per(N-formyl) macrocycles 5-7 were hydrolyzed under acidic conditions to give the unsubstituted polyaza macrocycles 8-10 in yields of over 77%.
