We have accomplished efficient synthesis of planar-chiral bridged 2,2′-bipyridine (S)-6, C2-symmetric bipyridinophane (S,S)-7, bridged 2,2′:6′,2″-terpyridines (S)-11, and C2-symmetric terpyridine (S,S)-12 by metal-mediated biaryl cross-coupling or homo-coupling reactions of the corresponding 6-halo[10](2,5)pyridinophanes. Stille-type and Negishi cross-coupling reactions are particularly useful for the syntheses of 6, 11, and 12. On the other hand, nickel-mediated homo-coupling reaction worked best for achieving the synthesis of structurally unique bipyridinophane 7.
