A regioselective synthesis of β- and γ-fluorinated ketones via silver-catalyzed ring opening is described. A variety of β- and γ-fluorinated ketones are efficiently prepared, respectively, from tertiary cyclopropanol and cyclobutanol precursors, providing a straightforward approach for the introduction of a fluorine atom into complex molecules. Preliminary mechanistic studies suggest that a radical-mediated sequential C-C bond cleavage and C-F bond formation pathway is involved.
本文描述了一种通过银催化开环反应实现β-和γ-氟代酮的区域选择性合成的方法。通过叔环丙烷和环丁醇前体，分别高效制备了各种β-和γ-氟代酮，为在复杂分子中引入氟原子提供了一种直接的方法。初步的机理研究表明，该反应涉及自由基介导的顺序 C-C 键断裂和 C-F 键形成途径。
