the direct conversion of aldehydes to thioesters via integration of organocatalysis and electrosynthesis. The thiazolium precatalyst was found to facilitate oxidation of thiolate anions, leading to deleterious formation of disulfide byproducts. By circumventing this competing reaction, thioesters were obtained in good-to-excellent yields for a broad range of aldehyde and thiol substrates. This approach
已经开发了一种通过有机催化和电合成的整合将醛直接转化为硫酯的方法。发现噻唑鎓前催化剂促进硫醇盐阴离子的氧化,导致二硫键副产物的有害形成。通过规避这种竞争性反应,对于各种醛和硫醇底物,均以良好至优异的收率获得了硫酯。这种方法提供了一种原子有效的硫酯化反应,从而无需化学计量的外源氧化剂,高细胞电势或氧化还原介体。
