SimplePhos ligands, e.g., I [R = Ph, 3-(F3C)C6H4, 3,5-Me2C6H3], represent a novel class of monodentate chiral ligands based on a chiral amine moiety and flexible diaryl groups on the phosphorous atom. They were easily prepared by two different pathways and could be highly functionalized. Their application as ligands in the copper-catalyzed asym. conjugate addition of di-Et zinc and trialkylaluminum reagents to cyclic enones, acyclic enones and nitroalkenes was reported, and resulted in giving high enantioselectivity with up to 98.6% ee. In particular, the reaction of trialkylaluminum reagents with a wide range of 3-substituted enones allowed the formation of stereogenic quaternary carbon centers.
