[n] (2,5) Pyridinophanes (I) have been synthesized by acid catalyzed cyclization of bis-(β-aminovinyl)-diketones to [n] (2,5) pyridinophan-n-ones (V), followed by WOLFF-KISHNER reduction. The conformational stability of the lower members (n < 12) of the series is shown by reduction of V to diastereomeric [n] (2,5) pyridinophan-n-ols (XI). In addition [9] (2,5) pyridinophane (I, n = 9) has been resolved
