The analogous three-component synthesis strategy for substituted 1,2,4-oxadiazole and quinazoline derivatives from readily available benzaldehyde, benzylamine and hydroxylamine or aniline has been developed. Both the cascade reaction sequences involves nucleophilic addition of C−N bond, introduction a halogen donor, nucleophilic substitution and Cu(II)-catalyzed aerobic oxidation. This synthesis methodology

生物的类似三组分合成策略。两个级联反应序列都涉及 CN 键的亲核加成、引入卤素供体、亲核取代和 Cu(II) 催化的有氧氧化。这种合成方法表现出良好的收率、广泛的底物范围和作为绿色氧化剂的
