Abstract

An efficient and practical synthetic method for the functionalized 2-amino hydropyridines and 2-pyridinones was successfully developed via the domino reactions of arylamines, methyl propiolate, aromatic aldehydes and the substituted acetonitriles with triethylamine as base catalyst. Reactions involving malononitrile and cyanoacetamide gave exclusively the 2-aminohydropyridines. On the other hand ethyl cyanoacetate resulted in the 2-pyridinones as main products.

摘要

成功开发了一种通过芳基胺、丙炔酸甲酯、芳香醛和取代的乙腈与三乙胺作为碱催化剂的串联反应来合成功能化的 2-氨基氢化吡啶和 2-吡啶酮的有效且实用的方法。涉及丙二腈和氰基乙酰胺的反应仅得到 2-氨基氢化吡啶。另一方面,氰基乙酸乙酯主要生成 2-吡啶酮。
