Abstract
The present invention relates to a method for preparing a carboxylic acid ester compound. Under the catalysis of nitrite, a carboxylic acid reacts with an alcohol in air so as to obtain an ester compound; and the alcohol is ethanol, propanol or trifluoroethanol. The present invention has the advantages such as mild reaction conditions, rich source of raw materials, wide universality of reaction substrates, and simple operation, and can modify a series of carboxylic acids having medicinal properties and aliphatic carboxylic acids such as biologically active amino acids.
