A novel and simple procedure was developed for the regioselective synthesis of α-bromo (di)ketones from electron-rich epoxides via visible light photoredox catalysis. Through optimization of solvent and light source, the reaction can be rapidly achieved under mild conditions. Moreover, the possible reaction mechanism was proposed and further supported by control experiments.
开发了一种新颖且简单的方法,用于通过可见光光氧化还原催化从富含电子的环氧化物中区域选择性合成α-溴(di)酮。通过优化溶剂和光源,可以在温和的条件下快速完成反应。此外,提出了可能的反应机理,并得到了对照实验的进一步支持。
