Cycloaddition coupling reactions of ethyl-5, 6-diphenyl-1, 2, 4-triazine-3-carboxylate with norbornenes and 7-oxanorbornenes

In this paper, reactions of substituted 1, 2, 4-triazines with norbornenes and 7-oxanorbornenes are described. Depending on the substrate and the reaction conditions, 1:1 or 2:1 deazetized cycloaddition products were obtained. Furthermore, a novel aza-isobenzofuran was prepared as an intermediate by flash vacuum pyrolysis of one on these adducts.
