Novel chiral tricyclic compounds were prepared from the reactions of the cystine dimethyl ester and 4-substituted 2,6-bis(chloromethyl)phenol derivatives. The 1H-NMR and CD spectra showed the existence of chiral twisting of the cyclophane unit, which was induced by the chirality of the cystine moiety.
