VERFAHREN ZUR RACEMISIERUNG EINES OPTISCH AKTIVEN LYSINALKYLESTER-DIHYDROCHLORIDS

An optically active lysine alkyl ester.dihydrochloride is racemized by heating at 100 DEG C. to 250 DEG C. under an atmosphere of hydrogen. By combining this process with asymmetric hydrolysis of racemic lysine alkyl ester with enzymes, racemic lysine alkyl ester can be converted all to L-lysine.
