A highly enantioselective reduction of α,β-unsaturated nitriles can be conducted by using a Cu(OAc)2/josiphos complex as the catalyst under hydrosilylation conditions. The reaction provides access to valuable β-aryl-substituted chiral nitriles in good yields and with excellent enantioselectivities.
