catalyzed synthesis of di- and triarylated all-carbon quaternary stereocenters via asymmetric allylic arylation (AAAr) with aryl organolithium compounds is demonstrated. The use of readily available or easily accessible aryl organolithium reagents in combination with trisubstituted allyl bromides, in the presence of a copper/NHC catalyst, affords important di- and triarylated all-carbon quaternary stereocenters
