Scaffold hybridization of several natural and synthetic anticancer leads led to the consideration of indenoindolones as potential novel anticancer agents. A series of these compounds were prepared by a diversity-feasible synthetic method. They were found to possess anticancer activities with higher potency compared to etoposide and 5-fluorouracil in kidney cancer cells (HEK 293) and low toxicity to corresponding normal cells (Vero). They exerted apoptotic effect with blocking of cell cycle at G2/M phase. (C) 2012 Elsevier Ltd. All rights reserved.

Friedel-Crafts reaction of 2-bromobenzoyl chlorides with indoles to give 3-(2-bromobenzoyl)indoles and their palladium-catalyzed intramolecular direct arylation to give indenoindolones, has been developed. 3-(2-Bromobenzoyl)indoles were crucial intermediates; the method was successful with N-unprotected or N-protected indoles. This approach affords a convenient preparation of diverse substituted and functionalized
