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
一些硝基烷烃、2-硝基丙烷、2-硝基丁烷、1-硝基丙烷和苯基硝基甲烷与溴乙酸甲酯在偶极非质子溶剂中的 O-烷基化产生 α-羟基-β-硝基羧酸盐,后者转化为 β-氨基-α-羟基羧酸。几种γ-氨基羧酸由相应的γ-硝基羧酸酯合成,这些γ-硝基羧酸酯是通过硝基烷烃与β-溴丙酸甲酯的C-烷基化获得的。
