Herein, a practical and effective synthesis of thioesters from readily available carboxylic acids and odorless disulfides was developed under photocatalytic conditions. This approach involves phosphoranyl radical-mediated fragmentation to generate acyl radicals and allows for incorporation of both S atoms of the disulfides into the desired products. In addition to batch reactions, a continuous-flow
在此,在光催化条件下开发了一种实用且有效的由容易获得的羧酸和无味二硫化物合成硫酯的方法。该方法涉及正膦基自由基介导的断裂以产生酰基自由基,并允许将二硫化物的两个S原子掺入所需的产物中。除了间歇反应外,还采用了连续流反应器,能够实现克级的快速硫酯合成。还展示了初步实验机制研究和 dalcetrapib 的快速合成。
