Synthesis of new bis(tetrahydropyrrolo[3,4-b]carbazoles) with a functionalized diaryl spacer

Mehrabani,Pindur

, p. 1406 - 1412 (2007/10/03)

Some new bis(tetrahydropyrrolo[3,4-b]carbazoles) were synthesized by Diels-Alder reactions of in-situ generated indole-2,3-quinodimethanes with a variety of bismaleimides as dienophiles and also by reaction of dianilines with a succinic acid anhydride group incorporated into a biscarbazole. In a special reaction a spermine linker was introduced. The new biscarbazoles represent potential DNA ligands for the development of new antitumor active drugs.
