three-component reaction involving elemental sulfur is disclosed for achieving a metal-free, oxidant-free synthesis of thioesters in a high atom-economical, step-economical and chemoselective manner. A mechanistic investigation indicates that the use of elemental sulfur to trap acyl radical derived from radical umpolung of α-keto acid with an electrochemical design can efficiently generate a carbonyl
公开了涉及元素硫的电化学三组分反应,用于以高原子经济性、步骤经济性和化学选择性的方式实现硫酯的无金属、无氧化剂合成。机理研究表明,通过电化学设计,使用元素硫捕获α-酮酸自由基翻转产生的酰基自由基,可以有效地产生羰基硫基自由基,该自由基可以进一步被重氮烷捕获,得到各种硫酯。
