Selective ring closures of p-tert-butylthiacalix[4]arene and p-tert-butylcalix[4]arene with oligoethylene glycols were performed under the Mitsunobu protocol using the DEAD/TPP system. The method opens a new perspective for the syntheses of 1,3-calixcrowns.
的选择性环封闭件对叔丁基硫[4]芳烃和对-叔丁基杯[4]芳烃与低聚乙二醇进行使用DEAD / TPP系统的Mitsunobu方案下进行。该方法为1,3-杯冠的合成开辟了新的前景。
