Gold-Catalyzed Intermolecular Markovnikov Hydroamination of Allenes with Secondary Amines
A cationic (CAAC)gold(I) complex promotes the addition of all types of nontertiary amines to a variety of allenes, affording allylic amines in good to excellent yields; the amino fragment always adds to the less substituted terminus of the CCC skeleton.
