title: Synthesis of some unsymmetrical bridged terpyridines.
abstract: Novel unsymmetrical terpyridines 1 and 2 are synthesized using intra- and intermolecular Michael additions as the key reactions, followed by the construction of the central pyridine ring. Terpyridine 1 represents a heretofore unknown hexacyclic ring system.
