摘　　要：采用1D和2D梯度场NMR技术(包括1D1H NMR,13C NMR,DEPT,2D1H-1HCOSY,HSQC,HMBC),对3,3′-二(2,4-二氯苯基)-2,4,2′,4′-四氧杂螺[5.5]十一烷的4个亚甲基呈现的4组裂分峰进行了明确的归属,也对化合物中其它1H和13C NMR谱信号进行了全归属,为四氧杂螺双缩醛类化合物的结构鉴定提供了充分依据.The molecular structures of pentaerythritol diacetals with ehiral axes were elucidated by 1D and 2D NMR techniques, including ^1H NMR, ^13C NMR, DEPT, ^1H-^1H COSY, HSQC and HMBC. The chemical environment of the eight hydrogen atoms in the four methylenes were analyzed. The ^1H and ^13C chemical shifts of 3, 3′-bis（2, 4-dichlorophenyl）-2, 4, 2′, 4′-tetraoxaspiro[5.5] undecane were assigned. The resuits should provide a basis for elucidating molecular structures of other pentaerythritol diacetals and diketals.
