摘要： The invention relates to a process for producing a 2-oxo-3-aromatic carboxylic acid derivative, which comprises reacting an aromatic pyruvic acid derivative with an electrophilic compound in a protic solvent in the presence of a base. This process can provide in good yields the 2-oxo-3-aromatic carboxylic acid derivatives which can be easily converted to aromatic amino acid derivatives or 2-aromatic alkanoic acid derivatives which are important intermediates for synthesizing medicines, agrochemicals, etc.
