Electron-donating substituted 3-cyanomethyl-2-vinylindoles were found to rearrange via thermal [1,5]H shift into the corresponding indole-2,3-quinodimethanes which were trapped by dienophiles to afford tetrahydrocarbazoles. (C) 2002 Elsevier Science Ltd. All rights reserved.
Synthesis and anticancer activity of new pyrrolocarbazoles and pyrrolo-β-carbolines
'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.
