A catalyst system derived from commercially available Pd2(dba)3 and PtBu3 enables the coupling of α-keto ester enolates and aryl bromides to provide an array of β-stereogenic α-keto esters. The derived products are of broad interest given the prevalence of the α-keto acid substructure in biologically important molecules.
