Formylating the amino nitrogen of an alkali metal salt of an amino carboxylic acid, by reacting the salt with an alkyl formate in an alkanol solvent. In one embodiment, the alkyl formate is added to the reaction as such; in another embodiment, the alkyl formate is formed in situ by reaction of carbon monoxide with the alkanol solvent in the presence of the alkali metal salt of the amino carboxylic acid. The process provides a new class of compounds, the alkali metal salts of N-formyl-aspartic acids.
通过将氨基羧酸的碱金属盐与烷基甲酸酯在烷醇溶剂中反应,对氨基碱金属盐的氨基氮进行甲酰化。在一种实施例中,烷基甲酸酯直接加入反应中;在另一种实施例中,通过在碱金属盐的氨基羧酸存在下,将一氧化碳与烷醇溶剂反应形成烷基甲酸酯。该过程提供了一类新的化合物,即N-甲酰天冬氨酸的碱金属盐。
