Process for separating the (R,S) racemate of cysteine |
| abstract |
To separate the racemate (R, S) -cysteine, it is condensed in an inert solvent with an enantiomerically pure monosaccharide from the group of aldoses with 4 to 7 carbon atoms to give the corresponding 2-substituted thiazolidine-4-carboxylic acid and the resulting mixture of diastereomers is separated from one another Cut. The isolated uniform diastereomers are then reacted in an inert solvent for ring cleavage with a carbonyl reagent and the enantiomerically pure cysteine obtained in each case is isolated as such or as the corresponding cystine. |
