摘要：

An enantioselective chemoenzymatic two-step one-pot transformation of styrene to 1-phenylethylamine has been developed based on combining an initial Pd/Cu-catalyzed Wacker oxidation of styrene with a subsequent reductive amination of the in situ formed acetophenone. As a nitrogen source only ammonia is needed. The incompatible catalysts were separated by means of a polydimethylsiloxane membrane, thus leading to quantitative conversion and an excellent enantiomeric excess of the corresponding amine. The overall one-pot process formally corresponds to an asymmetric hydroamination of styrene with ammonia.
