Abstract The systematic syntheses of 2-alkenylpyrazine N-oxides through palladium-catalyzed C-2 selective C H olefination reaction was disclosed. Various acrylate esters substituted pyrazine N-oxides were obtained in up to 93% yields. Thermogravimetric analysis indicated that the fracture temperature of particular compound 3 f was about 267 °C. The pyrolysis of compound 3 f could generate several aroma compounds such as 2,5-dimethylpyrazine, 2,3,5-trimethylpyrazine and benzyl alcohol. The results of the pyrolysis experiment perfectly proved the flavoring property of the products as potential flavor additives.
