Abstract

A new bambusuril derivative, , lacking substituents on the ureidic nitrogen atoms, has been isolated and characterized. This macrocycle was prepared by the deprotection of bambusuril . is attractive for use as a starting compound for the preparation of other bambusuril derivatives, which was demonstrated via propargylation and the copper-catalyzed click reaction performed on the macrocycle.

摘要

一种新的竹节环脲衍生物，在脲基氮原子上没有取代基，已被分离和表征。这种大环化合物是通过竹节环脲的脱保护制备的。作为制备其他竹节环脲衍生物的起始化合物，它很有吸引力，这通过在大环化合物上进行炔丙基化反应和铜催化的点击反应得到了证明。
