Pyrazine-2-substituted carboxamide derivatives: synthesis, antimicrobial and Leuconostoc mesenteroides growth inhibition activity [PDF]
Journal of the Serbian Chemical Society, 2006 Condensation of pyrazine-2,3-dicarboxylic acid anhydride with aminoacetophenones gave the corresponding N-(acetylphenyl)pyrazine-2-carboxamide. Their reactions with some electrophilic (carbonyl group, bromine) and nucleophilic (malononitrile, hydrazine ...

A Theoretical Study on the Photochemical Isomerization of 2,6-Dimethylpyrazine
Organics, 2022 DFT calculations on the photoisomerization of 2,6-dimethylpyrazine allowed us to confirm the role of benzvalene isomers in the isomerization of hexatomic heterocyclic compounds. 2,6-Dimethylpyrazine in the excited singlet states can be converted into the
