摘要：

A topologically chiral [2]catenane was synthesized and resolved by a diastereomer method. The [2]catenane consisting of a C-s symmetrical crown ether and a C-s symmetrical ammonium macrocycle was obtained as a racemic mixture. Introduction of a chiral auxiliary to the [2]catenane gave a diastereomeric mixture which was successfully resolved. Removal of the chiral auxiliary from both enantiomers of the [2]catenane gave rise to minor images of their CD spectra.
