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 convenient one-pot synthesis of 2-aroylindoles using a dominopalladium-catalyzed C,N-coupling/carbonylation/C,C-coupling sequence is described. The reaction involved easily prepared 2-gem-dibromovinylanilines and boronic acids under carbon monoxide. Optimized reaction conditions allowed the construction of a wide variety of highly functionalized 2-aroyl-/heteroaroylindoles in satisfactory yields
