of three-component reactions of various aromatic amines with a number of aldehydes and 1,3-diones was achieved. The unprecedented reaction involved a nucleophilic attack of an aromatic amine on the in situ generated Michael adduct intermediate followed by six-electron ring cyclizations. It is contrary to the common belief that advocates involvement of coupling reactions between a Knoevenagel adduct
进行了各种芳香胺与许多醛和1,3-二酮的三组分反应的机理研究。前所未有的反应涉及芳香胺对原位生成的迈克尔加合物中间体的亲核攻击,然后进行六电子环环化。与提倡在Knoevenagel加合物和芳族胺之间进行偶联反应以传递取代的四氢ac啶酮的普遍信念相反。
