(4R)-3-(Substituted aminoalkyl)oxycarbonyl-1,4-dihydro-2,6-dimethyl-4-(nitrophenyl)pyridine-5- carboxylic acids can be prepared efficiently, by reacting bis(substituted aminoalkyl) 1,4-dihydro-2,6-dimethyl-4-(nitrophenyl)pyridine-3,5-dicarboxylates with a microorganism capable of asymmetric hydrolysis and belonging to the genus Streptomyces, the genus Paecilomyces, the genus Botryodioplodia, the genus Alternaria or the genus Helminthosporium, or a treated product thereof. The compounds are extremely useful as important intermediates for preparation of pharmaceuticals useful for the prevention and treatment of angina pectoris, hypertension, etc.
通过将双(取代氨基烷基)1,4-二氢-2,6-二甲基-4-(硝基苯基)吡啶-3,5-二羧酸酯与一种能够不对称水解并属于链霉菌属、青霉菌属、葡萄孢属、交替孢属或镰刀菌属的微生物或其处理产物反应,可以高效制备(4R)-3-(取代氨基烷基)氧羰基-1,4-二氢-2,6-二甲基-4-(硝基苯基)吡啶-5-羧酸。这些化合物极为有用,是制备用于预防和治疗心绞痛、高血压等疾病的药物的重要中间体。
