A new approach for the synthesis of 2-vinylindole derivatives by 5-exo mode cyclization of 2-(3-silyloxymethylallenyl)anilines was developed. The starting allenylanilines were easily prepared by the Stille coupling of o-iodoaniline and allenylstannanes. The formed 2-vinylindole derivatives were transformed into several carbazole derivatives via the [4+2] cycloaddition reaction with suitable dienophiles
'Bended' 1, 3 or 'linear' 2 pyrrolidino-fused (aza)carbazoles were prepared and screened towards a few cancer-related targets. Whereas 'bended' derivatives I and 3 proved to be weakly toxic, several members of the 'linear' family strongly interact with DNA, especially derivative 28a. (c) 2005 Elsevier Ltd.
