| Abstract: | The condensation of 1,2-bishydroxylamines with 1,2-dicarbonyl compounds led to the isolation of derivatives of 2,3-dihydropyrazine-1,4-dioxide. The 2,3-bis(bromomethyl)-4a,5,6,7,8,8a-hexahydroquinoxaline reacts readily with O- and N-nucleophiles; condensed pyrazines are formed by interaction with o-phenylenediamine, phenylhydrazine, and tert-butylamine.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 4, pp. 514–522, April, 1993. |
