Highly enantioselective copper-catalyzed conjugate addition of diethylzinc to enones using chiral spiro phosphoramidites as ligands

Novel monodentate chiral spiro phosphoramidite ligands have been readily synthesized in good yields from enantiomerically pure 1,1′-spirobiindane-7,7′-diol. The new ligands were highly efficient in the copper-catalyzed conjugate addition of Et2
