Process for the chemical separation of racemic modifications of α-aminocarboxylic acid derivatives, and cinchonidine salt intermediates |
| abstract |
Racemic Modifications of α-aminocarboxylic acid derivatives, such as of α-amino-4-hydroxyphenylacetic acid derivatives, are prepared reliably and more economically than in known processes by reacting the DL-form of the derivative in a solvent with cinchonidine, isolating the precipitated cinchonidine salt and hydrolyzing said salt. |
