access to a range of cyclopropyl derivatives. Herein, we describe the development of a palladium-catalyzed α-arylation of cyclopropyl, cyclobutyl, and cyclopentyl nitriles that affords these functional groups in one step from a variety of aryl bromides in good to excellent yields. Furthermore, we demonstrate the transformation of aryl cyclopropyl nitriles into aryl trifluoromethyl cyclopropanes.
1,1-二取代的芳基环丙基腈在生物活性化合物中是有用的部分,并提供了一系列环丙基衍生物的途径。在这里,我们描述了环丙基,环丁基和环戊基腈的钯催化α-芳基化反应的开发,该反应可在一步骤中从多种芳基溴化物中以良好至极佳的产率提供这些官能团。此外,我们证明了芳基环丙基腈向芳基三氟甲基环丙烷的转化。
