含手性轴季戊四醇缩酮的合成及核磁解析

Synthesis and NMR Analysis of Pentaerythritol Ketal with Chiral Axis

合成了含手性轴的季戊四醇双缩酮(3,9-二甲基-3,9-二(4-硝基苯)-2,4,8,10-四氧杂螺[5.5]十一烷),目标化合物经元素分析、IR、1 H NMR、13C NMR表征及利用核磁二维谱对目标化合物的四个亚甲基的4组裂分峰进行了明确的归属。

In the study 3,9 -- Dimethyl -- 3,9 -- bis -- （4 -- nitro -- phenyl） -- 2,4,8,10 -- tetraoxa -- spiro [5.5-] undecane with Chiral Axis was synthesized, and characterized by IR,^1H NMR,^13C NMR, and elemental analysis was made. The ^1H chemical shifts of title compound were also completely assigned by 2D NMR.
