Article abstract of DOI:10.1248/cpb.45.863

Chiral 4-aryl-1,4-dihydro-2,6-dimethyl-3,5-pyridinedicarboxylates and 1,4-dihydro-2,4,6-trimethyl-3,5-pyridinedicarboxylate have been obtained in 80-99%ee by lipase catalyzed hydrolysis of bis(acyloxymethyl) 1,4-dihydro- 3,5-pyridinedicarboxylate in an H₂O/organic solvent system. These chiral dihydropyridines were readily converted into chiral drugs, such as nicardipine, felodipine and PCA 4248.
