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 tetrahydro-1,4-dioxino[2,3-b]pyrazine. Crystallographic data on the three-dimensional structures of these compounds were reported Держатели документа: Центральная научная библиотека УрО РАН Доп.точки доступа: Slepukhin, P. A.; Rusinov, G.
