  developed an unprecedented highly enantioselective N-heterocyclic carbene (NHC)-Pd catalyzed Suzuki-Miyaura cross-coupling reaction for the synthesis of atropisomeric biaryls. These reactions enable efficient coupling of aryl halides (Br, Cl) or aryl triflates and various types of aryl boron compounds (B(OH)2, Bpin, Bneo, BF3K), tolerate a remarkably broad scope of functional groups and heterocycles

  轴向手性联芳支架是化学中必不可少的结构单元。不对称 Pd 催化的 Suzuki-Miyaura 交叉偶联反应已被广泛认为是构建联芳阻转异构体的最实用方法之一。然而，该领域仍存在长期挑战。例如，底物范围通常狭窄且专门化，官能团和杂环会导致反应性和选择性降低，通常需要庞大的邻位取代基，并且报道的方法通常不适用于四邻位取代的联芳基。我们开发了一种前所未有的高对映选择性 N-杂环卡宾 (NHC)-Pd 催化的 Suzuki-Miyaura 交叉偶联反应，用于合成阻转异构联芳基化合物。这些反应使芳基卤化物（Br，Cl) 或芳基三氟甲磺酸酯和各种类型的芳基硼化合物（B(OH)2、Bpin、Bneo、BF3K），耐受范围非常广泛的官能团和杂环（>41 个例子），采用低负载催化剂（0.2- 2 mol%)，并在温和条件下进行。该协议以优异的对映选择性（高达> 99% ee）提供了对各种阻转异构联芳基和杂联
