  Boc Groups as Protectors and Directors for Ir-Catalyzed C−H Borylation of Heterocycles

  摘要：

  Ir-catalyzed C-H borylation is found to be compatible with Boc protecting groups. Thus, pyrroles, indoles, and azaindoles can be selectively functionalized at C-H positions beta to N. The Boc group call be removed on thermolysis or left intact during subsequent transformations.

• Merging Halogen-Atom Transfer (XAT) and Copper Catalysis for the Modular Suzuki–Miyaura-Type Cross-Coupling of Alkyl Iodides and Organoborons

  DOI：10.1021/jacs.1c12649

  日期：2022.2.2

  Suzuki–Miyaura-type cross-couplings between alkyl iodides and aryl organoborons. This process requires a copper catalyst but, in contrast with previous approaches based on palladium and nickel systems, does not utilizes the metal for the activation of the alkyl electrophile. Instead, this strategy exploits the halogen-atom-transfer ability of α-aminoalkyl radicals to convert secondary alkyl iodides into the

  我们在这里报告了一种机制上不同的方法来实现烷基碘和芳基有机硼之间的 Suzuki-Miyaura 型交叉偶联。该过程需要铜催化剂，但与以前基于钯和镍系统的方法相比，它不使用金属来活化烷基亲电试剂。相反，该策略利用 α-氨基烷基自由基的卤素原子转移能力将仲烷基碘转化为相应的烷基自由基，然后与芳基、乙烯基、炔基、苄基和硼酸烯丙酯物质偶联。这些新颖的偶联反应具有简单的设置和条件（室温下 1 小时），并有助于获得制药行业所针对的特权基序。
