procedure. Background experiments and mechanistic studies were also. performed to rationalize this cascade process. The usefulness of this methodology was finally demonstrated via the transformation of a series of α-sulfanyl-enone adducts through selected oxidation reactions, stereoselective synthesis of cyclopropyl ketones, indanones, and pyrazole compounds.
综合有用的Z-选择性级联甲硫基自由基加成、1,3-双键异构化、氧捕获反应,可以在可见光下被曙红B促进,从而以良好的产率构建2-芳基-和烷硫基烯酮衍生物。对不同硫醇的反应性和反应条件筛选的准确研究,使我们能够将该反应扩展到大量底物,显示出良好的官能团耐受性,同时突出了该过程的局限性。背景实验和机理研究也是如此。执行以合理化此级联过程。通过选择性氧化反应、环丙基酮、茚满酮和吡唑化合物的立体选择性合成转化一系列 α-硫烷基-烯酮加合物,最终证明了该方法的有效性。
