chemistry and industry. Despite the fact that the synthesis of alcohol-based carbamates has been well studied, an efficient access to hydroxamic acid-based carbamates is less explored due to the nucleophilicity of both O and N atoms in hydroxamic acids. Herein, we report a copper-catalyzed oxidative coupling of quinazoline-3-oxides and formamides for the synthesis of O-quinazolinic carbamates. This protocol
有机氨基甲酸酯代表了有机化学和工业中的一种特殊结构。尽管已经对醇基氨基甲酸酯的合成进行了充分研究,但由于异羟肟酸中 O 和 N 原子的亲核性,因此很少探索有效地获得基于异羟肟酸的氨基甲酸酯。在此,我们报道了一种铜催化的喹唑啉-3-氧化物和甲酰胺的氧化偶联,用于合成O-喹唑啉氨基甲酸酯。该协议具有实用性强、起始材料简单、操作简单等特点。
