Polycyclic Heterocycles with Acidic N-H Group, VI1. The synthesis of some polycyclic heterocyclic compounds related to 3-phenyl-1,2-dihydro-quinoxaline-2-one
Original language description
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 wereprepared 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) andazocoupling 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).

Czech 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]triazinya 1,3-diaminopyrazoly.
