Abstract
The racemates of newly synthesized 4-aryl-1,4-dihydropyridine derivatives attracting interest in the treatment of coronary insufficience were resolved via the formation of diastereomeric salts. In order to check the quality of the preparative resolution, capillary electrophoresis using neutral cyclodextrins (CDs) was developed. In particular, the α-CD was found to be a powerful discriminator of the enantiomers. Additionally, taking amlodipine and nicardipine into consideration, a mechanism of the chiral recognition with α-CD could be proposed.
