Synthesis of Seven- and Eight-Membered Ring-Annulated Pyridines by “Inverse” Intramolecular Diels-Alder Reaction with Trifluoromethyl-Substituted 1,2,4-TriazinesIntramolecular [4 + 2] cycloaddition reactions with inverse electron demand of trifluoromethyl-substituted 1,2,4-triazines carrying 7- or 8-membered o-alkyne side-chain dienophiles (3,8,12) lead to the synthesis of bicyclic pyridines with annulated heterocyclic seven- (5, 9, 13-15) or eight-membered rings (19, 22, 23, 26).
