Abstract
A new and selective palladium-catalyzed amination of the pyrido[3′,3′:4,5]pyrrolo[1,2-c]pyrimidine nucleus, the heterocyclic core of the variolin alkaloids, is described. The method allows the introduction of amino and aryl- and alkylamino substituents on the C9 position in advanced precursors of variolin B and deoxyvariolin.
