There is a process for producing 2-oxo-3-aromatic carboxylic acid derivatives which comprises reacting aromatic pyruvic acid derivatives with electrophilic compounds in the presence of bases in a protic solvent. According to this process, 2-oxo-3-aromatic carboxylic acid derivatives which can be easily converted to aromatic amino acid derivatives or 2-aromatic carboxylic acid derivatives as important synthetic intermediates of medicines and agricultural chemicals can be produced in good yields with high selectivity.
有一个生产2-氧代-3-芳香羧酸衍生物的过程,其中包括在质子溶剂中存在碱的情况下,用亲电性化合物反应芳香丙酮酸衍生物。根据这个过程,可以以高选择性的良好产率生产2-氧代-3-芳香羧酸衍生物,这些衍生物可以轻松转化为芳香氨基酸衍生物或2-芳香羧酸衍生物,作为药物和农业化学品的重要合成中间体。
