Synthesis of 5H-Pyrazino[2,3-b]indoles from Indole-2,3-dione Derivatives.
摘要:
Reaction of N-acetylindol-2,3-diones with ethylenediamines gave the dihydro-pyrazinones 11, which could, after dehydrogenation and deacetylation be transformed to the corresponding 5H-pyrazino[2,3-b]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-b] indole.
