The synthesis of rotaxanes featuring two dipyrromethane stoppers, which differ in thread length and rigidity, is presented. The condensation of the precursor rotaxanes with acetone was found to be influenced by the axle's structural facets. As a result, the calix[4]phyrin-based macrocyclization strategy produced [2]-, [3]-, and [4]catenanes, depending on the specific structure of the rotaxane substrate.
本文介绍了具有两个二吡咯甲烷封端基的轮烷的合成，这两个封端基在链长和刚性上有所不同。发现前体轮烷与丙酮的缩合受轴的结构方面的影响。因此，基于杯[4]卟啉的大环化策略根据轮烷底物的具体结构产生了[2]、[3]和[4]连环烷。
