The crown ether 11 has a trimethylammonium group reaching into the interior of the cavity and is complexed intramolecularly by short CH—O hydrogen bonds. Additional hydrogen bonds between the acidified CH3 groups and the iodide anion were confirmed by X-ray analysis.

The absolute stereochemical course of the enantioselective Diels-Alder reactions can be rationalized on the basis of the mechanistic model previously described for the reaction of a,/3-enals and cyclopentadiene with a catalyst in which a formyl CH - O hydrogen-bond provides additional organization of the transition state [25,35]. On the basis of that analysis, there are two possible approaches of cyclopentadiene to the...

CH- O hydrogen-bonding between crown ether and l,2-bis(pyridini-um) ethane is strong enough to construct rotaxanes [75]. A few oligorotax-anes were obtained from the oligo 1,2-bis(pyridinium)ethane and DB24C8 [76] (Scheme 13).
