  Copper-Facilitated Suzuki Reactions: Application to 2-Heterocyclic Boronates

  摘要：

  The palladium-catalyzed Suzuki-Miyaura reaction has been utilized as one of the most powerful methods for C-C bond formation. However, Suzuki reactions of electron-deficient 2-heterocyclic boronates generally give low conversions and remain challenging. The successful copper(l) facilitated Suzuki coupling of 2-heterocyclic boronates that is broad in scope Is reported. Use of this methodology affords greatly enhanced yields of these notoriously difficult couplings. Furthermore, mechanistic investigations suggest a possible role of copper in the catalytic cycle.
