The sequential use of Cu-catalyzed asymmetricallylic alkylation, olefin cross-metathesis, and Ir-catalyzed asymmetricallylic amination allows the concise, stereodivergent synthesis of complex chiral amines with complete regiocontrol and good diastereoselectivity, exemplified by the synthesis of a pair of diastereoisomeric unnatural branched amino acid derivatives.
