Synthesis of 5H-pyrazino[2,3-b]indoles from indole-2,3-dione derivatives
Reaction of N-acetylindol-2,3-diones with ethylenediamines gave the dihydropyrazinones 11, which could, after dehydrogenation and deacetylation, be transformed to the corresponding 5H-pyrazino[2,3-e]indoles 5. N,N-Dimethylaminoethylation of the anion of 5 occurred selectively in the 5-position. Thermolysis of 1-pyrazinylbenzotriazole gave pyrazino[1,2-a]-benzimidazole 33 and no 5H-pyrazino[2,3-e]indole. Acta Chemica Scandinavica 1997.
