The First Cyclodiasteromeric [3]Rotaxane
Abstract
A mechanically linked molecule, consisting of an axle and two equivalent wheels, shows an analogous stereochemistry to the classical example tartaric acid. Though the components are not chiral themselves, a (cyclo)diastereomeric species is obtained, the enantiomers (shown schematically) and the meso form of which were completely separated and chiroptically characterized.
