A novel method for electrochemical lactonization via C(sp3)–H functionalization was developed. This metal- and oxidant-free strategy enabled the efficient synthesis of various lactones. Gram-scale reaction and derivatization of the lactone product demonstrated the synthetic utility of this methodology. Mechanistic studies using control experiments and CV curves elucidated the proposed intramolecular
开发了一种通过 C( sp 3 )–H 官能化进行电化学内酯化的新方法。这种不含金属和氧化剂的策略能够有效合成各种内酯。内酯产物的克级反应和衍生化证明了该方法的合成效用。使用对照实验和 CV 曲线进行的机理研究阐明了所提出的分子内 HAT 和氧化环化途径。通过这种电化学方法实现了不寻常的肖诺型氧化,无需传统的亲核加成过程。
