An efficient acid-catalyzed approach to the synthesis of functional 1,4-dihydropyridines from the reaction of readily available enaminones with aldehydes has been developed. This methodology was realized by a cascade reaction involving first formation of divinylmethanes and subsequent intramolecular cyclization.
已开发出一种有效的酸催化方法,可通过容易获得的烯胺酮与醛的反应合成功能性 1,4-二氢吡啶。这种方法是通过级联反应实现的,包括首先形成二乙烯基甲烷和随后的分子内环化。
