Abstract : Chiral 2,16-diallyl-, 2,16-dimethyl- and 2,16-di-t-butylpyridino-18-crown-6 ligands have been prepared by treating the appropriate chiral a,a'-disubstituted pyridinedimethanol with tetraethyleneglycol ditosylate in the presence of base. In these reactions, chiral 2:2 dimers (dipyridino-36-crown-12 derivatives) were also obtained.
