In order to obtain N-benzyl-3,5-dicarbethoxy-2,6-dimethyl-4-phenyl-1,4-dihydropyridine 1 as a lead compound of pharmacological interest, the classical Hantzsch synthetic method and the modified Collie procedure were used. However, only a very low yield of 1 was obtained in a mixture with larger amounts of some by-products (2, 3, 4). Compound 1 was then synthesized in satisfactory yield via a different
为了获得具有药理学意义的先导化合物N-苄基-3,5-二碳乙氧基-2,6-二甲基-4-苯基-1,4-二氢吡啶1,使用了经典的Hantzsch合成方法和改进的Collie方法。然而,在具有大量一些副产物(2、3、4)的混合物中,仅获得非常低的产率1。然后通过另一种方法以令人满意的产率合成化合物1,以及另一种副产物(9)。阐明了所有副产物的结构,并描述了导致此类化合物形成的可能机理。
