Process for the resolution of racemic alpha-aminonitriles |
| abstract |
Process for the resolution of certain racemic α-aminonitriles into optically active enantiomers which includes treating the racemic α-aminonitriles with (-)-mandelic acid in an alkanol/C 5-8 hydrocarbon mixture to obtain a racemic mixture of diastereoisomeric D and L salts of (-)-mandelic acid, macerating the salts with an alkanol/C 5-8 hydrocarbon mixture; neutralizing the L-form; extracting the neutralized product; and converting it into a stable form. |
