Polyethereal macrocycles were prepared from both 2, 6-dichloro-1, 5-naphthyridine(2) and 2, 7-dichloro-1, 8-naphthyridine (6). The" cross-the-face" structures of 1: l macrocycles 7, derived from 2, were confirmed by NMR. The 2, 7-(l, &naphthyridmo) macrocyclic structures 9 and 10 were also supported by NMR data which were indicative of diminished N-electron density, when compared to the parent 1, 8-naphthyridine. Template reactions did not ...
