Abstract
Optically active amino acids N-acylated with carboxylic acids are readily racemized without decomposition at elevated temperature in inert organic solvents in which they are homogeneously soluble at the racemization temperature. When the deacylated amino acid is insoluble or only sparingly soluble in the solvent, the method permits a convenient work-up of the products of enzymatic deacylation of one enantiomorph of the N-acylamino acid in which the remaining enantiomorph is racemized for recycling to the deacylation step.
