11-Hydroxyindeno[1,2-c]isoquinotines 12a-c were prepared as constrained forms of 3-arylisoquinolines through an intramolecular cyclization reaction. Among the synthesized compounds, the 11-butoxy analog 15I displayed potent in vitro cytotoxicity against four different tumor cell lines as well as topoisomerase I inhibitory activity. A FlexX docking study was performed to explain the topoisomerase I activity of 151. (c) 2007 Elsevier Ltd. All rights reserved.
Cobalt-Catalyzed Dual Annulation of<i>o</i>-Halobenzaldimine with Alkyne: A Powerful Route toward Bioactive Indenoisoquinolinones
A cobalt‐catalyzed dualannulation reaction for the synthesis of variously substituted indenoisoquinolinones from 2‐bromobenzaldehydes, amines, and methyl 2‐(ethynyl)benzoates has been developed. This method could also be applied to the synthesis of an array of highly functionalized bioactiveindenoisoquinolinones and their derivatives. A possible mechanism of the cobalt catalysis is proposed, involving
