Herein, we describe a copper photoredox catalyzedsynthesis of acetamide via regioselective C–Ncoupling of arylamines with terminal alkynes using molecular oxygen (O2) as an oxidant at room temperature under visible light irradiation (47 examples). Unique simultaneous formation of both amide and ester functionalities occurs via intramolecular cyclization in a single-step reaction in the case of anthranilic
本文中,我们描述了在室温下在可见光照射下,使用分子氧(O 2)作为氧化剂,通过芳基胺与末端炔烃的区域选择性C–N偶联,通过铜的光氧化还原催化乙酰胺的合成(47个例子)。在邻氨基苯甲酸的情况下,使用便宜的铜作为催化剂,使用环保的O 2作为氧化剂和试剂,通过一步一步反应通过分子内环化,可以同时形成酰胺和酯官能团。18 O 2证明,不同的底物经历不同的反应途径以生成相似的乙酰胺产物。标记实验。当前的方案也适用于快速,少步制备生物活性抑制剂(BACE-1和PDE4)。这个过程可以很容易地放大到克级,绿色度量的计算表明了当前光氧化还原方法的经济可行性和生态友好性。

A practicalsynthesis of valuable N-acyl anthranilic acids has been achieved via a silver-catalyzed imino-ketene generation from readily available anthranils and carboxylic acids. A wide range of carboxylic acids including sterically demanding aliphatic carboxylic acids, aromatic carboxylic acids, acrylic acids, and amino acids are compatible in this reaction. Moreover, this method can be used to modify
