- Synthesis of Mutagenic Methyl- and Phenyl-substituted 2-Amino-3H-imidazoquinoxalines via 2,1,3-Benzoselenadiazoles
-
2-Amino-3-methyl-3H-imidazoquinoxaline, all its derivatives with 1-4 methyl groups in positions 4, 5, 7 and 8, and 2-amino-3,5-dimethyl-7,8-diphenyl-3H-imidazoquinoxaline have been synthesized from the corresponding 6-methylamino-5-nitroquinoxalines through reduction and cyclization with cyanogen bromide.The quinoxalines were obtained from the appropriate α-dicarbonyl compounds and 4-methylamino-3-nitro-1,2-benzenediamines.The latter were prepared from 4-halo-1,2-benzenediamines via 2,1,3-benzoselenadiazoles.The 7- and 8-phenyl derivatives of 2-amino-3,5-dimethyl-3H-imidazoquinoxaline have been synthesized in a slightly different way.
