Due to boron’s metalloid properties, aromatic boron reagents are prevalent synthetic intermediates. The direct borylation of aryl C-H bonds for producing aromatic boron compounds offers an appealing, one-step solution. Despite significant advances in this field, achieving regioselectivearyl C-H bond borylation using simple and readily available starting materials still remains a challenge. In this

Not a trace: Borylation of the nitrogen in nitrogen heterocycles or anilines provides a tracelessdirectinggroup for subsequent catalytic CHborylation. Selectivities that previously required Boc protection can be achieved; furthermore, the NBpin directinggroup can be installed and removed in situ, and product yields are substantially higher. Boc=tert‐butoxycarbonyl, pin=pinacolato.
无痕:氮杂环或苯胺中氮的硼酸化为随后的催化 C H 硼酸化提供了一个无痕导向基团。可以实现以前需要 Boc 保护的选择性;此外,NBpin导向基团可以原位安装和拆卸,产品收率显着提高。Boc=叔丁氧基羰基,pin=频哪醇。
