Abstract:
5-Alkynyl-6-aryl-2,2′-bipyridines were conveniently prepared in two steps comprising oxidative SN H ethynylation of 5-aryl-3-(2-pyridyl)-1,2,4-triazines at position 6. At the second step, the 1,2,4-triazine moiety was transformed into the pyridine one employing aza-Diels–Alder reaction with 2,5-norbornadiene.
Keywords:
nucleophilic substitution of hydrogen, 1,2,4-triazines, acetylenes, 2,2′-bipyridines, aza-Diels–Alder reaction.
