Abstract
Copper complexes of phosphoramidites efficiently catalyzed asymmetric addition of arylboron reagents to acyclic enones. 1,4-Insertion of arylcopper(I) led directly to O-bound copper enolates, which makes the mechanism fundamentally different from classical oxidative addition/reductive elimination.
