  sp³ C−H Bond Arylation Directed by Amidine Protecting Group:  α-Arylation of Pyrrolidines and Piperidines

  摘要：

  A new ruthenium-catalyzed direct sp3 C-H to C-C bond transformation is disclosed. Specifically, a method for the alpha-arylation of cyclic amines, containing either permanent (pyridine, pyrimidine) or removable (amidine) directing groups, is described. This cross-coupling reaction involves heating amine substrates with arylboronate ester at 150 degrees C in a ketone solvent with a catalytic amount of ruthenium carbonyl [Ru3(CO)12]. Arylboronate esters containing either electron-withdrawing or electron-donating substituents could be efficiently coupled. Heteroarene boronates were also effective donors.

  need is an open vial! The direct α arylation of cyclic alkylamines (see scheme) requires an open vial, as the hydrogen atom involved in the C(sp3)H‐activation process is ultimately released as hydrogen gas. Reports on the formation of hydrogen gas in direct transition‐metal‐catalyzed functionalizations are still rare. Open‐vial reactions proved crucial to this direct arylation procedure as, upon sealing

  您只需要一个开放的小瓶！环状烷基胺的直接α芳基化反应（请参见方案）需要一个开放的小瓶，因为参与C（sp 3）H活化过程的氢原子最终会以氢气的形式释放出来。关于在直接过渡金属催化的官能化反应中形成氢气的报道仍然很少。小瓶反应证明对这种直接芳构化过程至关重要，因为密封后会发生催化剂失活。
