Novel bis(tetrahydropyrrolo[3,4-b]carbazoles) linked with aliphatic chains: synthesis and structural aspects

Syntheses of novel bis(tetrahydropyrrolo[3,4-b]carbazoles) by a [4+2]cycloaddition reaction are described. By variation of dienophiles bis(tetrahydropyrrolo[3,4-b]carbazoles) of varying aliphatic spacer length could be obtained in high yields. These conformationally highly flexible molecules represent an interesting class of compounds, believed to have an affinity towards DNA, as potential DNA ligands.
