摘要：
The interaction of 3-alkanoylquinoxalin-2-ones with 1,2-phenylenediamines in boiling acetic acid led to the contraction of the pyrazine ring as the result of a quinoxaline-benzimidiazole rearrangement with the formation of 2-benzimidazolyl-substituted quinoxalines. © 2007 Springer Science+Business Media, Inc.
