✦ Synopsis

A new methodology for the synthesis of functionalised 2,2%:6%,2%%-terpyridine systems is suggested: sequential synthesis of the heterocyclic assemblies based on the 1,2,4-triazine ring, direct introduction of the cyano group in the 1,2,4-triazine ring and the transformation of the latter to a pyridine ring via an aza-Diels-Alder reaction.

A novel four step process for the preparation of symmetric terpyridines is presented. The title compound, 2,2':6',2"-terpyridine (la) and a substituted derivative, 5,5"-dimethyl-2,2':6',2"terpyridine (lb) are prepared. Both la and lb share a common precursor, 2,6-diacetylpyridine (2) and are prepare
