Photocatalyst‐free Photoredox Arylation of Quinoxalin‐2(1H)‐Ones with Aryldiazo Sulfones

Electrochemical Oxidative Arylsulfonylation and 1,2‐Alkyl Shift Sequences of Alkenyl Cyclobutanols for the Synthesis of β‐Sulfonated Cyclopentanones

“…As part of the research program investigating the redox reactions of aromatics and alkene derivatives, 5k‐5s,9 we recently reported the radical‐mediated functionalization of aromatics and alkenes by anodic oxidation 10 . In this communications, we wish to report the electrochemical oxidative arylsulfonylation/1,2‐alkyl shift sequences of alkenyl cyclobutanols.…”

Recent Advances in Arylations and Sulfonylations of Arylazo Sulfones

“…近年来, 特别是 3 位取代喹喔啉酮 吸引人们的广泛合成兴趣 [24] . 2018 年, Kim 教授课题 组 [25] 发展了可见光诱导下芳基偶氮砜与喹喔啉酮 C(3) 2019 年, 邱頔课题组 [27] 亚砜是极有价值的含硫有机化合物, 它不仅大量存 在于天然产物和药理活性化合物中, 而且还常常用于构 建各种重要药物分子. 其传统合成方法主要依赖于硫醚 的氧化, 涉及使用金属试剂和化学计量的高价碘或过氧 化物氧化剂.…”

Recent Advances on the Catalytic Functionalization of Quinoxalin- 2(1H)-ones via C-H Bond Activation

“…In the same year, Kim and coworkers also developed successfully a photocatalyst-free photoredox arylation of quinoxalin-2(1H)-ones with aryldiazo sulfones (Scheme 16). [38] The reaction was completed without any other metal, oxidant, or additives. The proposal protocol was a facile way for the synthesis of 3-arylquinoxalin-2(1H)-one derivatives with a wide range of functional group tolerance.…”
