The O-alkylation of some nitroparaffins, 2-nitropropane, 2-nitrobutane, 1-nitropropane, and phenylnitromethane, with methyl bromoacetate in dipolar aprotic solvent led to α-hydroxy-β-nitrocarboxylates, which were converted into β-amino-α-hydroxycarboxylic acids. Several γ-aminocarboxylic acids were synthesized from the corresponding γ-nitrocarboxylates which were obtained via C-alkylation of the nitroparaffins
