… /palladium-catalyzed Suzuki–Miyaura coupling of heteroaryl halides with 3-pyridine-and 3-thiopheneboronic acid: an efficient catalyst for the formation of biheteroaryls
Heteroaryls are ubiquitous in biologically active compounds.[1–4] However, for electronic or poisoning reasons, they are not good reactants.[5–7] Palladium-catalyzed Suzuki–Miyaura coupling is a powerful and synthetically valuable process for the preparation of heteroaryl derivatives.[8–11] In recent years, much work has been directed toward the coupling of arylboronic acids with heteroaryl halides,[12–16] but the reactions involving ...
