A copper-catalyzed decarboxylative regioselective protocol for the synthesis of 1,5-disubstituted 1,2,3-triazoles through direct annulation of cinnamic acids with aryl azides has been developed. This is the first example of 1,5-disubstituted 1,2,3-triazoles, under aerobic conditions using Cu(II) as the catalyst, which were generally synthesized using a ruthenium(II) catalyst. The simplicity and regioselectivity
已经开发了一种铜催化的脱羧区域选择性方案,用于通过肉桂酸与芳基叠氮化物的直接环合反应合成1,5-二取代的1,2,3-三唑。这是在有氧条件下使用Cu(II)作为催化剂的1,5-二取代1,2,3-三唑的第一个例子,通常使用钌(II)催化剂合成。这种方法的简单性和区域选择性补充了经典的CuAAC,催化了1,4-二取代的1,2,3-三唑的合成。
