O-directed alkyne trans-haloboration using BX3 (X=Cl or Br) leads to C4-halogenated benzoxaborinines that are useful intermediates for accessing the core structure found in bicyclic boronate based β-lactamase inhibitors. A computational study identified two viable mechanisms to furnish the trans-haloboration products.
使用 BX 3 (X = Cl 或 Br)的O 定向炔烃反式卤硼化产生 C4 卤代苯并氧硼酸,它是获取基于双环硼酸盐的 β-内酰胺酶抑制剂中发现的核心结构的有用中间体。一项计算研究确定了两种可行的机制来提供反式卤化产物。
