Abstract
The reaction of 1,4-dihydroxyanthraquinone with ethylenediamine in the presence of Cu(I)Cl or Cu(II)Cl2 gave 6-hydroxy-1,2,3,4-tetrahydronaphtho- (2, 3-f) -quinoxaline- 7,12-dione in quantitative yield at ambient temperature. The reaction was promoted greatly by copper ions. The possible mechanism and the role of copper ions were discussed.
