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.
手性4-芳基-1, 4-二氢-2, 6-二甲基-3, 5-吡啶二甲酸酯和1, 4-二氢-2, 4, 6-三甲基-3, 5-吡啶二甲酸酯的产率为80-99% ee 通过在 H2O/有机溶剂系统中脂肪酶催化双(酰氧基甲基) 1, 4-二氢-3, 5-吡啶二甲酸酯的水解得到。这些手性二氢吡啶很容易转化为手性药物,如尼卡地平、非洛地平和 PCA 4248。
