A highly enantio- and regioselective copper-catalyzed hydroamination reaction of alkenes with hydroxylamine esters in the presence of diethoxymethylsilane enables the conversion of a wide variety of substituted styrenes, including trans-, cis-, and β,β-disubstituted styrenes, to yield α-branched amines. In addition, aliphatic alkenes gave exclusively the anti-Markovnikov hydroamination products.
