摘要：

Carbon acids, in particular malonates, malononitrile, and anthranone, react enantioselectively with anitroalkenes in the presence of Takemoto's organocatalyst in liquid carbon dioxide medium (100 bar, rt), under homogeneous conditions, to afford the corresponding Michael adducts in moderate to high yields and with enantioselectivities comparable with those obtained in organic solvents.
