文摘

Through-the-annulus-catenated calixarenes have been obtained, for the first time, by exploiting the 鈥渟uperweak anion鈥?approach that allows the threading of the calix cavity with functionalized dialkylammonium axles. In addition, the first example of a stereoprogrammed synthesis of a catenane orientational isomer (an oriented calix[2]catenane) has been obtained, after macrocyclization, by using a directional alkylbenzylammonium axle.
