FIELD: chemistry.
SUBSTANCE: invention relates to a method of producing α-hydroxycarboxylic acids, particularly a novel method of producing 2-hydroxy-carboxyalkyladamantanes of general formula 
where R=H, CH3, which can be used as intermediate products in synthesis of adamantyl-containing amino acids and heterocyclic compounds. The method includes reacting adamantanone-2 with dilithium salts of acetic or propionic acid, obtained in situ by reacting lithium acetate or propionate with lithium hexamethyldisilylamide, obtained beforehand from hexamethyldisilazane and phenyllithium, in the medium of dry tetrahydrofuran at 20-45°C and molar ratio hexamethyldisilazane: lithium acetate or propionate: adamantanone-2 of 1.3-1.4:1.8-2.1:1.
EFFECT: wider range of compounds of the disclosed structural formula and obtaining products with high output and high degree of purity.
