γ-Ethoxycarbonyl-γ-nitroketones (V) and (X) were prepared by the Michael condensation of α, β-unsaturated ketone (III) and ethyl nitroacetate or by the application of ethyl nitroacetate to β-tert-amino ketone (IV) or (IX). Catalytic reduction of these compounds with Raney nickel as a catalyst afforded several kinds of ethyl pyrroline-2-carboxylate derivatives, and their structures were discussed.
