α-Keton sulfides are versatile building blocks in organic synthesis. From thioic acids and alkenes, we were able to develop the direct synthesis of α-keton thiol esters via photocatalytic oxidative radical additions. This reaction well matches the idea of green chemistry. It takes the advantage of thioxanthone as an inexpensive organic photocatalyst, O2 as a green oxidant, EtOAc as a green solvent
α-酮硫化物是有机合成中的多用途构建单元。从硫代酸和烯烃,我们能够通过光催化氧化自由基加成开发 α-酮硫羟酸酯的直接合成。这个反应很符合绿色化学的理念。它利用噻吨酮作为廉价的有机光催化剂,O 2作为绿色氧化剂,EtOAc作为绿色溶剂,可见光作为可持续能源,唯一的副产物是水。
