Palladium-catalyzed ring opening of aminocyclopropyl Ugi adducts
Abstract
The ring opening of aminocyclopropanes triggered by activation with an intramolecular arylpalladium(II) iodide complex is an interesting strategy for the synthesis of nitrogen heterocycles and a valuable Ugi postcondensation-type transformation. Six- and seven-membered-ring cyclic enamines may be obtained. © Georg Thieme Verlag Stuttgart * New York.
