Js. You et al., Synthesis of new chiral macrocyclic tetraoxo polyamines containing pyridine ring and functional arms, SYN COMMUN, 29(14), 1999, pp. 2447-2455
Seven new chiral macrocyclic tetraoxo polyamines containing pyridine ring a
nd functional arms derived from L-histidine, L-alanine, L-leucine and L-phe
nylalanine, respectively, have been synthesized and characterized by MS,H-1
NMR and elemental analysis.
