To address the need for a more general catal)Tic method of s)mthesizing allylic ammonium ylides for [2,3]-rearrangements that is amenable to enantioselective catalysis, our group recently developed a palladium-catalyzed tandem allylic amination/[2,3]-Stevens rearrangement of tertiary amines that proceeds through a palladium-n-allyl intermediate rScheme 15.34T Metal-catalyzed allylic aminations between primary or secondary amines... [Pg.578]
