A simple, green and cost-effective protocol has been devised for the synthesis of
4-substituted-2,6-dimethyl-3,5-pyridinecarboxylates from Hantzsch-type 1,4-dihydropyridines via
rapid oxidation in excellent yields using 1.5 equivalent of ceric ammonium nitrate within 15 minutes in
solvent-free conditions. The method was able to furnish the products in excellent yields. The products
obtained were characterized by their NMR and melting points data.
一种简便、绿色且经济的合成方法已被设计出来,用于从汉奇型1,4-二氢吡啶通过快速氧化合成4-取代-2,6-二甲基-3,5-吡啶羧酸盐,使用1.5当量的硝酸铈铵在无溶剂条件下15分钟内实现优异的产率。该方法能够以优异的产率提供产物。所得产物通过其核磁共振和熔点数据进行表征。
