US Patent 7790900 Method for producing an optically active nitro compound

An optically active nitro compound having two hydrogen atoms on its α-carbon atom and having β-asymmetric carbon atom can be produced by making α,β-unsaturated nitroolefin having a hydrogen atom on its α-carbon atom react with at least two organosilicon compounds having at least one silicon-hydrogen bond in the molecule in the presence of an asymmetric copper complex, or react with an organosilicon compound having at least one silicon-hydrogen bond in the molecule in the presence of an asymmetric copper complex and water.
