An enantioselective conjugate addition of 2-acylimidazoles with nitroalkenes catalyzed by chiral-at-metal rhodium(III) complex under mild reaction conditions was developed, affording versatile γ-nitro ketone skeletons in good yields with excellent enantioselectivities (up to >99% ee). (Figure presented.).
DNA-based catalytic enantioselective Michael reactions in water

High, but not dry: A highly enantioselective Michael reaction in water has been developed by using a simple DNA-based catalyst. Enantioselectivities of up to 99% ee could be obtained by using nitromethane and dimethyl malonate as the nucleophiles and αf,β-unsaturated 2-acylimidazoles as the Michael acceptors. The reactions can be performed on a preparative scale and the catalyst can be recycled. (Chemical Equation Presented).
