Abstract
The readily functionalized ligands, BINAM-PHOS, participate in the copper-catalyzed asymmetric conjugate addition of organozinc reagents to enones. The incorporation of benzoyl derivatives on nitrogen atoms was crucial to promote the reaction. Notably, BINAM-PHOS derivatives gave the opposite major enantiomers to that obtained using BINOL-PHOS derivatives, which we have developed for the construction of multinuclear catalysts.
