Abstract

Abstract Suitable substituted 1, 2, 4-triazines as Mell as 1, 2, 4, 3-tetrazines carrying 7- membered ω-alkyne sidechain dienophiles react in an intramolecular Diels-Alder cycloaddition mith inverse electron demand to yield the corresponding novel bicyclic pyridines pyridazines, respectively.
