Abstract:

Products of diaddition of O- and C-nucleophiles to the 2,3-dicyano-1-ethylpyrazinium cation were isolated for the first time. The tandem AN-AN reactions of 2,3-dicyano-1-ethylpyrazinium tetrafluoroborate with 1,3-diketone enolates or keto esters afforded tetrahydrofuro{[}2,3-b]pyrazine derivatives, whereas cyclization with ethylene glycol gave tetrahydro1,4-dioxino{[}2,3-b]pyrazine. Crystallographic data on the three-dimensional structures of these compounds were reported.
