Abstract: Racemic mixtures of previously unknown chiral “tweezers” with a rigid asymmetrical diazocine bridge (Troger base) were synthesized on the basis of 4,4'-diaminodiphenyl sulfone. The Troger base was condensed with 2,4-dihydroxybenzaldehyde and 4-formylbenzoic acid to obtain new aromatic chelate cavities.
