title: Recognition properties of acyclic glycoluril oligomers.
abstract: The fragmentation reaction of bis-nor-seco-CB[10] with 3,5-dimethylphenol (3) delivers methylene bridged glycoluril pentamer 5 in 81% yield. The host-guest recognition properties of the previously known tetramer 4 and those of pentamer 5 and hexamer 6 toward cationic guests in water are used to delineate some important features of the binding of acyclic CB[n]-type receptors.
