direct C–H β‐carbonyl alkylation of heteroarenes has been achieved through K2S2O8‐mediated ring‐opening of cyclopropanols. A wide scope of substrates, such as various substituted quinolines and isoquinolines, pyridines, pyridazine, benzo[d]thiazole, and phenanthroline, underwent the β‐carbonyl alkylation efficiently and afforded the β‐heteroarylated ketones in moderate to excellent yields.
无金属直接C-H β羰基杂芳烃烷基化已到K达到2小号2 ö 8介导的cyclopropanols的开环。各种各样的底物,例如各种取代的喹啉和异喹啉,吡啶,哒嗪,苯并[d]噻唑和菲咯啉,有效地进行了β羰基烷基化反应,并以中等至优异的产率提供了β杂芳基化的酮。
