Abstract: The solvent effect on the 1H chemical shifts of N,N'-dicarboxymethyl macrocyclic ether-bislactones was investigated. The experiments show the 1H chemical shifts of methylenes a、b、c in the title compounds (1-4) which increase with the solvent polarity. The instability of the compound 1 was confirmed by 1H NMR method. The characteristics of 13C NMR spectra of compound 4 due to slow conformation exchange were also discussed in this paper.
