A facile and practical protocol for C–H phosphorothiolation of indolizines using thiocyanate as the sulfur source and phosphite as the phosphorylated reagent has been developed. A broad range of substrates were well tolerated and the desired products were obtained in moderate to excellent yields. Moreover, the reaction involved electrochemical thiocyanation of indolizines and a chemical process to construct
已经开发出一种简便实用的中氮茚的 C-H 硫代磷酸化方案,使用硫氰酸盐作为硫源,亚磷酸盐作为磷酸化试剂。多种底物具有良好的耐受性,并且以中等至优异的产率获得了所需的产物。此外,该反应涉及中氮茚的电化学硫氰化以及在 DBU 存在下构建 S-P 键的化学过程。循环伏安法和对照实验揭示了该反应的合理 EC 机制。该方法为室温电化学氧化合成-(杂)芳基硫代磷酸酯提供了一条绿色途径,无需外部氧化剂和过渡金属催化剂。
