将水杨醇在ＤＭＦ中与ＮａＨ和二甘醇或三甘醇二对甲苯磺酸酯反应，合成了２个新的二苯并冠醚（１和２）．其结构由元素分析和波谱分析所表征。１经Ｘ射线衍射分析确定为反位构型．提出了合成反应的机理。
Salicyl alcohol was reacted with NaH and diethylene glycol or triethylene glycol di-p-toluenesulfonate in DMF to synthesize two new dibenzo crown ethers (1 and 2). Its structure is characterized by elemental analysis and spectral analysis. 1 was confirmed by X-ray diffraction analysis as the inverse configuration. The mechanism of synthesis reaction was proposed.
