efficient methods for the synthesis of naphthalimides with structural diversity. In this work, we developed a new approach for the synthesis of naphthalimides via a tandem reaction of o-methylbenzaldehydes and maleimides. The tandem reaction involves Pd(II)-catalyzed benzylic C(sp3)–H oxidation using an amino acid as the transient directing group and Diels–Alder reaction. The subsequent dehydration
萘二甲酰亚胺在材料科学和制药领域有着广泛的应用。仍然非常需要开发有效的方法来合成具有结构多样性的萘二甲酰亚胺。在这项工作中,我们开发了一种通过邻甲基苯甲醛和马来酰亚胺的串联反应合成萘酰亚胺的新方法。串联反应涉及使用氨基酸作为瞬时导向基团的Pd(II) 催化的苄基 C(sp 3 )–H 氧化和 Diels-Alder 反应。随后脱水形成萘二甲酰亚胺。该反应引入酰亚胺部分并同时构建苯环,从而可以轻松获得一系列具有各种取代基的萘酰亚胺。
