Description	Tato práce se zabývá reaktivitou některých 3-(2-aminofenyl)-1,2-dihydrochinoxalin-2-onů. Diazotací těchto aminů a kopulací s ethyl kyanoacetylkarbamátem nebo malonodinitrilem byly připraveny hydrazony, které byly převedeny na odpovídající [1,2,4]triaziny a 1,3-diaminopyrazoly. (cs) This work deals with the study of reactivity of some 3-(2-aminophenyl)-1,2-dihydroquinoxaline-2-one (4) which were prepared by the reaction of N-acetylisatines (2a-2c) with 1,2-diaminobenzene and further hydrolysis of acetyl group. Compounds 2d, 2e were prepared by the reaction of isatines 1d, 1e with 1,2-diaminobenzene. Cyclization reaction of (4) in POCl3 afforded indolo[2,3-b]quinoxaline (7a-7e). Intramolecular coupling reactions of diazonium salts (5) lead to [1]benzofuro[2,3-b]quinoxalines (6) and azocoupling reactions of diazonium salts (5) with ethyl cyanoacetyl carbamate and malonodinitrile gave arylhydrazones (9) and (10). These arylhydrazones were then transformed to [1,2,4]triazines (11) and 1,3-diaminopyrazoles (12).
