polarity and revealing expanded reactivity patterns. Through this analysis formalism, polarity matching has been established for Rh(III)-catalyzed N-amino-directed C–H coupling with 3-methyleneoxetan-2-ones, providing efficient access to 1,2-dihydroquinoline-3-carboxylic acids. The identified reaction, by virtue of the internal oxidative mechanism, showcases mild reaction conditions (room temperature),
本文提出动态极性分析作为研究静态极性和瞬态极性并揭示扩展反应模式的通用工具。通过这种分析形式,为 Rh(III) 催化的N-氨基定向 C-H 与 3-亚甲基氧杂环丁烷-2-酮的偶联建立了极性匹配,从而有效地获得 1,2-二氢喹啉-3-羧酸。所确定的反应凭借内氧化机制,表现出温和的反应条件(室温)、短的反应时间(2小时)和普遍较高的产物产率。
