Achiral and chiral imidazoliophanes were prepared by N-alkylation of chiral imidazole derivatives featuring an-amino acid motif and subsequent double quarternization of the imidazole N3-position of the corresponding precyclophanes. Eight new optically pure imidazoliophanes were synthesized in good yields, whereas the molecular structure of one achiral analogue was confirmed by X-ray analysis.
