A copper-catalyzed regioselective hydroamination of α,β-unsaturated phosphonates has been developed to form corresponding α-aminophosphonates of interest in medicinal chemistry. The introduction of an umpolung, electrophilic amination strategy with the hydroxylamine derivative is the key to achieving the α-amination regioselectivity, which is otherwise difficult under the conventional nucleophilic
