developed methodology rendered the use of carboxylic acids as a direct surrogate of primary amines, for the synthesis of primary ureas, secondary/tertiary ureas, O/S-carbamates, benzoyl ureas, amides, and N-formyls, exploiting the Curtius reaction. This approach has a potential to provide a diversified library of N-containing compounds, starting from a single carboxylic acid, based on the selection of the
在本文中,我们报告了使用常规合成方法将灭活的羧酸单锅多步转化为各种含N的化合物的过程。发达的方法论使用羧酸作为伯胺的直接替代品,利用库尔蒂斯(Curtius)反应合成伯脲,仲/叔脲,O / S-氨基甲酸酯,苯甲酰脲,酰胺和N-甲酰基。基于亲核试剂的选择,该方法具有提供从单一羧酸开始提供多样化的含N化合物库的潜力。
