    • There are also several reports of rotaxanes with oriented threads, rings and stereogenic elements present in the overall framework. The question of the inherent chirality of the objects and of their stereoselective synthesis was however not addressed: X.-Q. Li M.-X. Jia X.-Z. Wang X.-K. Jiang Z.-T. Li G.-J. Chen Y.-H.

    • The overall lack of stereoselective induction from the chiral stopper makes the distinction of the two diastereomeric species not necessary (see below).
