FIELD: chemistry.
SUBSTANCE: invention relates to a method of producing N-betulonoyl-ω-amino acids of formula 1, in which the end product is obtained by reacting ester hydrochloride ω-amino acid in presence of triethylamine for 10–14 hours with pre-treated water solution of betulonoyl chloride in organic solvent, followed by hydrolysis of ester group with water-alcohol alkali. 
n = 1, 2, 3.
EFFECT: disclosed is a method of producing N-betulonoyl-ω-amino acids, in which amount of solvent is reduced, non-toxic solvent is used for hydrolysis, emissions to environment are reduced.
