construction of amide bonds via a selective cleavage of C–H and CC bonds in indole structures using an iodine-promoted approach was developed. Mechanistic studies indicated the formation of superoxide radicals obtained from molecular oxygen activation as a key intermediate step, which provided a precursor for subsequent oxidative ring-opening and intermolecular cyclization. A broad range of quinazolin-4(3H)-ones
一种通过选择性裂解 C-H 和 C 直接构建酰胺键的高效方法 使用碘促进的方法开发了吲哚结构中的 C 键。机理研究表明,分子氧活化形成超氧自由基是一个关键的中间步骤,为后续的氧化开环和分子间环化提供了前体。在温和且环境友好的条件下,以中等至良好的收率合成了多种喹唑啉-4(3 H )-酮和色胺酮。
