| titleOfInvention | Diastereomer salts of phenylalanine and N-acyl derivatives thereof and process for the separation of optically active phenylalanine and N-acyl derivatives thereof |
| abstract | The present invention relates to the separation of optically active phenylalanine and N-acyl derivatives thereof and novel diastereomer salts of the said compounds. n According to the invention a racemic compound of the formula ##STR1## is reacted with an optically active resolving agent of the formula ##STR2## in a polar solvent and/or a mixture of solvents comprising at least one apolar solvent and optionally an achiral acid or base, thereafter n (a) when using the D-isomer of the resolving agent of the formula II, the crystalline diastereomer salt formed with the L-isomer of the compound of the formula I is separated, or n (b) when using the L-isomer of the resolving agent of the formula II, the crystalline diastereomer salt formed with the D-isomer of the compound of the formula I is separated, and n the enantiomers of the compound of the formula I from the diastereomer salt or the mother liquor are liberated by the aid of an achiral acid or base and the optically active product is separated in crystalline form. |
