Synthesis of new chiral macrocyclic tetraoxo polyamines containing pyridine ring and functional arms

摘要

Seven new chiral macrocyclic tetraoxo polyamines containing pyridine ring and functional arms derived from L-histidine, L-alanine, L-leucine and L-phenylalanine, respectively, have been synthesized and characterized by MS, ~1H NMR and elemental analysis.
