Fig. 37. Sanders acetylcholine-host catenane (S,S)8-(S)-79 assembled by hydrazone formation under dynamic conditions in the presence of the guest. Single diastereomer shown is for illustrative purposes; the absolute configuration of the product was not determined. (S,S) stereodescriptors refer to all covalent stereocentres in macrocycle framework. Emboldened S descriptor refers to the topological stereogenic unit. Highest priority atoms in each component are highlighted in black.
