their application as nucleophiles is limited to only a few reactions, and reactions utilizing α-aminomaleimides as asymmetric Michael donors have not been reported to date. Thus, in this work, asymmetric Michael addition of α-aminomaleimides as Michael donors to β-nitrostyrenes was conducted for the first time using an organocatalyst derived from a Cinchona alkaloid.

马来酰亚胺通常用作常规反应中的亲电试剂;然而,它们作为亲核试剂的应用仅限于少数反应,迄今为止还没有报道利用 α-氨基马来酰亚胺作为不对称迈克尔供体的反应。因此,在这项工作中,首次使用衍生自金鸡纳生物碱的有机催化剂,将作为迈克尔供体的 α-氨基马来酰亚胺与 β-硝基苯乙烯进行不对称迈克尔加成。密度泛函理论研究对于提高加合物的对映选择性至关重要。
