The synthesis of dipyrrolo[3,4-a:3,4-c]carbazole-1,3,4.6-tetraones, structurally related to granulatimide is reported. These compounds can be considered as granulatimide analogues in which a maleimide heterocycle replaces the imidazole moiety. The synthesis of pyridino[2,3-b]dipyrrolo[3,4-e:3,4-g]indole-1,3,4,6-tetraones is also reported. In these compounds, a 7-azaindole unit replaces the indole moiety present in the granulatimide and isogranulatimide structures. (c) 2005 Elsevier Ltd. All rights reserved.
