pharmaceutical molecules. Herein, we report metal-free, electrochemical, highly chemo- and regioselective synthesis of gem-diselenides through the coupling of α-keto sulfoxonium ylides with diselenides. The versatility of the electrochemical manifold enabled the selenylation with ample scope and broad functional group tolerance, as well as setting the stage for modification of complex bioactive molecules.

有机硒化合物是药物分子的重要支架。在此,我们报道了通过α-酮基亚砜叶立德与二硒化物的偶联,实现了无金属、电化学、高度化学和区域选择性合成偕二硒化物。电化学歧管的多功能性使得硒基化具有足够的范围和广泛的官能团耐受性,并为复杂生物活性分子的修饰奠定了基础。详细的机理研究表明,关键的 C-Se 键是通过电合成方案使用n -Bu 4 NI 作为电解质和催化剂构建的。最后,所需的α-酮宝石-二硒化物对白色念珠菌表现出优异的抗菌活性,可以将其确定为进一步探索的先导化合物。
