The synthesis of a topologically chiral in,out-bis-sulfonamide catenane and its "dimer" are reported. The structures of the amide wheel and of the catenane were resolved by X-ray analysis. NMR-titration of the monosulfonamide-wheel yielded conclusive association constants supporting the proposed reg
By use of an asymmetric Ullmann coupling involving chiral naphthalene oxazolines 1, the title compounds were prepared in good yields and with high diastereoselectivity. Hydrolysis of the binaphthyl oxazolines 2 led to the di-aldehydes 5, which were transformed into the azepine derivative, 6. The lat
