Process for the hydrolytic ring cleavage of thiazolidine derivatives to give 2-aminomercaptan derivatives and carbonyl compounds, which comprisesbringing an aqueous solution of the thiazolidine derivative into contact with an acidic cation exchanger in the H+ form, giving a solution L1 which contains the carbonyl compound andeluting the cation exchanger with a suitable eluent, giving a solution L2 which contains the 2-aminomercaptan derivative. |
