A Mild Metal‐Free Approach for the Direct Synthesis of Carbamoyl Azides from Carboxylic Acid Redox Active Esters
Advanced Synthesis and Catalysis(2024)
摘要
Carbamoyl azide is a pivotal compound used in the transformation into urea and amines, as well as in nitrene insertion reactions. In this study, we present a pioneering method for synthesizing carbamoyl azide directly from acid redox active esters without the use of metals or oxidants. This approach demonstrates tolerance for various functional groups, enhancing its applicability. Furthermore, this technique facilitates late‐stage modifications of natural products and pharmaceuticals, thereby accelerating the development and identification of novel drug candidates.
