摘　　要：报道Ｎ，Ｎ′－二羧甲基大环醚双内酯（１－４）１ＨＮＭＲ溶剂效应，１ＨＮＭＲ跟踪的稳定性研究，溶剂极性影响标题化合物构象互变而表现为１３Ｃ谱线特征．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 13 C NMR spectra of compound 4 due to slow conformation exchange were also discussed in this paper.
