An optically active nitro compound having two hydrogen atoms on its α-cabon atom and having β-asymmetric carbon atom can be produced by making α, β-unsaturated nitroolefin having a hydrogen atom on its α-cabon atom react with at least two organosilicon compounds having at lest 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.

β,β-Disubstituted nitroalkenes readily undergo palladium-catalyzed [3 + 2] cycloaddition with trimethylenemethane to generate nitrocyclopentanes in excellent yield and enantioselectivity. The reaction provides access to heavily substituted cyclopentanes containing up to three contiguous stereocenters, and the products may be converted to both cyclopentylamines and cyclopentenones. A rare dependence

We document the use of a new catalyst system for the enantioselectiveconjugatereduction of nitroalkenes utilizing commercially available CuF(2) and the bis-phosphine JOSIPHOS as a ligand. This new protocol not only facilitates ready access to a variety of optically active nitroalkanes, but the results provide also new insight into copper-catalyzed reactions. [reaction: see text]

peptidomimetics. A single new organocatalyst provides high selectivity and substrate generality that is matched only by a combination of metal and organocatalysts. Within organocatalysis, this discovery breaks a 16-year monolithic paradigm, uncovering a powerful new scaffold for enantioselective reduction with behavior that suggests the recognition of a nitroethylene minimal catalaphile.
