METHOD FOR PRODUCING L-HOMOSERINE Russian patent published in 2023 - IPC C07C227/18 C07C229/22 B01J31/08 B01J31/10 

FIELD: chemistry.

SUBSTANCE: invention relates to a method for producing L-homoserine. Method involves the stage of bringing an L-homoserine derivative represented by the Formula 1 into contact with water and a solid acid catalyst. In the Formula 1, R₁ constitutes R_a-(C=O)-, R_a constitutes a substituted or unsubstituted alkyl group with 1 to 6 carbon atoms, a substituted or unsubstituted alkenyl group with 1 to 6 carbon atoms, a substituted or unsubstituted alkynyl group with 1 to 6 carbon atoms, a substituted or unsubstituted cycloalkyl group with 3 to 10 carbon atoms, a substituted or unsubstituted aryl group with 6 to 20 carbon atoms, or a substituted or unsubstituted heteroaryl group with 2 to 10 carbon atoms, and the substituents of the alkyl group, alkenyl group, alkynyl group, cycloalkyl group, aryl group, and heteroaryl group each independently constitute a halogen, a carboxyl group (-COON), an acetyl group (-COON₃), an amino group (-NH₂), a nitro group (-NO₂), a cyano group (-CN), an alkyl group with 1 to 6 carbon atoms, an aryl group with 6 to 10 carbon atoms, or a cycloalkyl group with 3 to 10 carbon atoms.

EFFECT: possibility of producing highly pure L-homoserine with a high degree of extraction.
