Synthetic studies of α,β-unsaturated α-nitrocarboxylic esters and the corresponding α-amino compounds are described. When α,β-unsaturated carboxylic ester was treated with fuming nitric acid, two products, α,β-unsaturated α-nitrocarboxylic ester and α-hydroxy-β-nitrocarboxylic ester, were formed. The former was converted into β-methoxy-α-nitrocarboxylic ester by treatment with methanol in the presence
描述了 α,β-不饱和 α-硝基羧酸酯和相应的 α-氨基化合物的合成研究。α,β-不饱和羧酸酯用发烟硝酸处理后,生成α,β-不饱和α-硝基羧酸酯和α-羟基-β-硝基羧酸酯两种产物。前者在甲醇钠或醋酸钠等碱存在下用甲醇处理,转化为β-甲氧基-α-硝基羧酸酯。用铝汞齐还原 β-甲氧基-α-硝基羧酸酯并随后蒸馏产物,得到 α,β-不饱和 α-氨基羧酸酯和 α-羟基氨基-β-甲氧基羧酸酯,它们的 N-邻苯二甲酰甘氨酰衍生物证实了这一点。
