The racemization of optically active aminoacids (including their N-acyl derivatives) by heating with carboxylic acids takes place particularly readily with carboxylic acids of low volatility. Only catalytic quantities of acid are needed; it is advantageous to use equimolar quantities or an excess, which serves as a diluent. A reaction mixture from an enzymatic racemate resolution can be heated directly for the purpose of racemization, after separation of the L-aminoacid and the water. |
