Abstract

Efficient addition: Bisphosphane–CuI complexes catalyze the enantioselective reduction of β,β-disubstituted nitroalkenes, giving chiral β,β-disubstituted nitroalkanes in useful yields and selectivities (see scheme). The reaction can be carried out with as little as 0.1 mol % of complex, rendering the process among one of the more efficient methods for conjugate addition chemistry.
