| titleOfInvention | ISOMERIZATION PROCEDURE. |
| abstract | Process for obtaining an isomer of a compound of the general formula (I): R-CH (CN) -R ', in which R and R' can each represent an organic radical linked directly, or through a heteroatom, to the carbon atom carrying the cyano group, provided that R and / or R 'comprises at least one dissolved chiral center, remaining stable under the conditions of the process, or a racemic modification comprising the isomer and its enantiomer. This method comprises treating the epimer of the isomer, or the racemate comprising the epimer and the enantiomer of the epimer, in solution in a polar organic solvent or as a slurry in a polar organic liquid diluent in which the epimer or the racemate is partially soluble, with a source of cyanide ions, in the absence of a base; the isomer, or the racemic modification comprising the isomer and its enantiomer being less soluble in the solvent or the diluent than the epimer of the isomer, or the racemate comprising respectively the epimer of the isomer and the enantiomer of the epimer. |
