Isomeric 2,6-pyridino-cryptands based on dibenzo-24-crown-8

Cryptands 4 and 5 were synthesized from cis- and trans-bis(hydroxymethylbenzo)-24-crown-8 by reaction with pyridine-2,6-dicarboxylic acid chloride in 42 and 48% yields, respectively. The new cryptands form pseudorotaxanes with the paraquat derivative N,N'-bis(beta-hydroxyethyl)-4,4'-bipyridinium bis...
