Palladium-Catalyzed Addition of Potassium Aryltrifluoroborates to Aliphatic Nitriles: Synthesis of Alkyl Aryl Ketones, Diketone Compounds, and 2-Arylbenzo[<i>b</i>]furans
developed, leading to a wide range of alkylarylketones with moderate to excellent yields. Moreover, several dinitriles (e.g., malononitrile, glutaronitrile, and adiponitrile) were applicable to this process for the construction of 1,3-, 1,5-, or 1,6-dicarbonyl compounds. The scope of the developed approach is successfully explored toward the one-step synthesis of 2-arylbenzo[b]furans via sequential
已经开发了钯催化的芳基三氟硼酸钾加成到脂肪族腈中的方法,从而产生了范围广泛的烷基芳基酮,并具有中等至极好的收率。此外,几种二腈(例如丙二腈,戊二腈和己二腈)适用于该方法,用于构建1,3-,1,5-或1,6-二羰基化合物。通过顺序加成和分子内环化反应,一步一步合成2-芳基苯并[ b ]呋喃已成功探索了所开发方法的范围。该方法学接受了广泛的底物,并适用于文库合成。

Palladium-Catalyzed Reaction of Arylboronic Acids with Aliphatic Nitriles: Synthesis of Alkyl Aryl Ketones and 2-Arylbenzofurans
yields under the standard conditions. An efficient palladium-catalyzed addition of arylboronic acids to aliphatic nitriles has been developed, providing a wide range of alkylarylketones in moderate to excellent yields. It is noteworthy that sequential addition and intramolecular annulation reaction of 2-(2-hydroxyphenyl)acetonitriles with arylboronic acids are also conducted smoothly to afford 2-arylbenzofurans
