Abstract

The reaction of 3-amino-4-(3,4-dimethoxyphenyl)maleimide  and  the methyl esters of 3-amino-4-(3,4-dimethoxyphenyl)-5-R-thiophene-2-carboxylic  acids with carbonyl compounds and nitrous acid has been investigated. Dioxopyrrolo[3,4-c]- and thieno[3,4-c]isoquinolines and cinnolines were obtained.
