FIELD: chemistry.
SUBSTANCE: invention relates to an enantioselective method of producing derivatives of sulfoxides and their salts. The method involves enantioselective oxidation of a sulphide of general formula (I) given below: A-CH2-S-B (I), in which A is a differently substituted pyridinyl ring and B is a heterocyclic residue which contains an imidazopyridinyl ring, with an oxidising agent in the presence of a catalyst based on titanium(IV) and a chiral ligand, which is a cyclic beta- or gamma-amino acid, in an organic solvent with subsequent conversion into salt using a base, if necessary.
EFFECT: obtaining sulfoxides and their salts with asymmetry on the sulphur atom level, which gives one or another enantiomer with good selectivity.
