Chirality is transferred from 12 stereogenic centers, all of the same chirality, to the six templating zinc(II) ions in each enantiomer of an optically active Borromeate. Recognizing that the three-component Borromean link is topologically achiral, J. F. Stoddart et al. describe in their Communication on page 4099 ff. the dynamic stereospecific synthesis of both all-R and all-S enantiomers of the Borromeate and report the X-ray crystal structure of the all-R enantiomer.
