Catalytic methylnaphthyl(XPhos)-palladium bromide promotes the coupling of chiral tert-leucine-derived Schöllkopf bis-lactim ether with cheap aryl chlorides at room temperature in yields up to 95 % and >25 : 1 dr. This enables a convenient access to non-natural tertiary arylglycines, which are key structural motifs in several top-selling drugs. This protocol is also suitable for the late-stage functionalization
