diversities of bench-stable and easy-to-use sulfonium salts and arenesulfonyl chlorides. Both developed methods, namely the light-mediated photoredox and electrophilic arylation, showed good efficiency, and are feasible for the preparation of 3-arylchromones in good-to-excellent yields. This work showcases the first described attempt where the sulfonium salts and arenesulfonyl chlorides were successfully utilized
本文中,我们公开了三种新方法,这些方法可通过大量稳定和易于使用的sulf盐和芳烃磺酰氯将邻羟基羟基亚胺基芳基化后,直接有效地合成3-芳基色酮。两种开发的方法,即光介导的光氧化还原和亲电芳基化,均显示出良好的效率,并且对于以良好至优异的产率制备3-芳基色酮是可行的。这项工作展示了首次描述的尝试,其中成功地利用了salts盐和芳烃磺酰氯来构建色酮杂环系统。
