  • Patent number: 11319565
    Abstract: The disclosure discloses a method for preparing a lipoamino acid compound based on deep eutectic solvents, and belongs to the field of organic synthesis. The preparation method of the disclosure uses a fatty acid and an amino acid as substrates, uses a deep eutectic solvent as a medium, and directly and efficiently prepares a single-chain lipoamino acid surfactant under the catalysis of lipase CALB. Alternatively, Amano lipase M is used as a catalyst to efficiently catalyze the reaction of an amino acid containing a plurality of amino groups with a fatty acid to prepare a Gemini amino acid. The method of the disclosure does not need to undergo protection and deprotection of the amino acid, and does not involve commonly used fatty acid chlorides. Compared with the traditional chemical synthesis methods, the disclosure has the advantages of greenness, safety, high selectivity, high yield, etc., and has very important potential application value.
