through a domino palladium-catalyzed sequence from 2-gem-dibromovinylanilines substituted by three methoxy groups and arylboronic acids under carbon monoxide atmosphere. These novel heterocycliccombretastatinA4analogues were evaluated for their cell growth inhibitory properties and their ability to inhibit the tubulin polymerization.

A simple procedure for the synthesis of 2-aroylindole derivatives comprising a one-pot CuI-catalyzed SNAr reaction of o-bromochalcones with sodium azide and subsequent intramolecular cyclization through nitrene C-H insertion has been developed. This protocol is also applicable with the 2'-bromocinnamates giving the indole-2-carboxylates.
