Two chiral bambusurils, which are diastereomers to each other, show remarkable differences in their binding affinity and selectivity toward inorganic anions as determined by isothermal titration calorimetry. These differences are explained by quantum-chemical calculations.

A general strategy for the synthesis of 2N,4N'-disubstituted glycoluril enantiomers on a multigram scale using orthogonal protection is reported. The use of these glycolurils is demonstrated in the synthesis of enantiomerically pure bambus[6]uril macrocycles. Moreover, the deprotection of (S)-1-phenylethyl substituents on the macrocycle was achieved, opening access to various chiral bambus[6]urils via post-macrocyclization modification strategy.
