Abstract

Conditions for the Suzuki-Miyaura coupling of lithium triisopropyl borates are reported, as well as a procedure for a one-pot lithiation, borylation, and subsequent Suzuki-Miyaura coupling of various heterocycles with aryl halides. These borate species are much more stable toward protodeboronation than the corresponding boronic acids and can conveniently be stored on benchtop at room temperature.

摘要

报告了三异丙基硼酸锂与Suzuki-Miyaura 偶联的条件,以及一种一锅法锂化、硼酸化和随后与各种杂环芳烃卤化物进行 Suzuki-Miyaura 偶联的方法。这些硼酸酯比相应的硼酸稳定得多,不容易发生脱硼反应,方便在室温下在实验台上储存。
