  Enantioseparation of racemic organic ammonium perchlorates by a silica gel bound optically active di-tert-butylpyridino-18-crown-6 ligand

  摘要：

  Both enantiomers of the novel chiral di-tert-butylpyridino-18-crown-6 ligand (R,R)-7 and (S,S)-7 containing an allyloxy group on the pyridine subcyclic unit were prepared by the reaction of 4-allyloxy-2,6-pyridinedimethyl ditosylate 9 and the enantiomers of di-tert-butyl-substituted tetraethylene glycol (R,R)-8 and (S,S)-8 in the presence of a strong base. One of them, (R,R)-7, was covalently attached to silica gel, and this chiral stationary phase (CSP) separated four selected racemic organic ammonium perchlorates into their enantiomers by column chromatography.
