reactions were then carried out. As a result, a series of triptycene-derived calix[5]arene derivatives in fixed cone and 1,2-alternate conformations were obtained. Moreover, conformation transformations of triptycene-derived calix[5]arenes from cone to 1,2-alternate forms could also be achieved.
Triptycene 衍生的 p-dibromocalix[5] 芳烃是通过片段偶联方法合成的,而对含有三个对叔丁基苯酚基团和一个 1,8-dimethyltriptycene 部分的三苯乙烯衍生的杯 [5] 芳烃的处理溴在二氯甲烷中在室温下直接产生三苯乙烯衍生的对五溴环[5]芳烃。然后进行甲基醚化和 Suzuki 偶联反应。结果,获得了一系列固定锥和1,2-交替构象的三苯乙烯衍生的杯[5]芳烃衍生物。此外,还可以实现三苯乙烯衍生的杯[5]芳烃从锥形到1,2-交替形式的构象转换。
