由水杨醇衍生的二苯并冠醚的合成和构型

Syntheis and configuration of Dibenzo-Crown Ethers Derived from Salicyl Alcohol

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。

Two dibenzocrown ethers(1 and2) were synthesized by the reaction of salicyl alcohol with NaH and di-and triethyleneglycol ditosylates in DMF, Their structures were characterized by elemental analysis, IR,1HNMR and MS. Dibenzo-20-crown ether(1)was confirmed as anti-configuration by the X-ray diffraction analysis of its single crystal.According to the configuration of 1, the reaction mechanism of the synthesis is proposed.
