ABSTRACT A fast and convenient protocol for the synthesis of a new class of piperidin-1-ium 6-amino-4-aryl-3,5-dicyano-1,4-dihydropyridine-2-thiolate (piperidinium salt) derivatives is developed by the one-pot, three-component reactions of cyanothioacetamide, aromatic aldehydes and piperidine in dichloromethane at room temperature. The features such as operational simplicity, mild conditions, absence
摘要开发了一种快速便捷的合成新型哌啶-1-鎓6-氨基-4-芳基-3,5-二氰基-1,4-二氢吡啶-2-硫醇盐(哌啶鎓盐)衍生物的方案。氰硫代乙酰胺、芳香醛和哌啶在室温下在二氯甲烷中的一锅三组分反应。该方案具有操作简单、条件温和、无催化剂、反应时间短、纯化过程简单、无需色谱技术等特点,极具吸引力。图形概要
