AbstractWe report a convenient method for the highly site-selective borylation of 8-arylquinoline. The reaction proceeds smoothly in the presence of a catalytic amount of [Ir(OMe)(cod)]2 and 2-phenylpyridine derived ligand using bis(pinacolato)diborane as the borylating agent. The reactions occur with high selectivity with many functional groups, providing a series of borylated 8-aryl quinolines with good to excellent yield and excellent selectivity. The borylated compounds formed in this method can be transformed into various important synthons by using known transformations.
我们报告了一种方便的方法,用于高度位点选择性地对8-芳基喹啉进行硼化反应。在[Ir(OMe)(cod)]2和2-苯基吡啶衍生的配体存在下,使用双(二甲基苯基)二硼烷作为硼化试剂,反应顺利进行。这些反应在许多官能团的高选择性下发生,提供了一系列硼化的8-芳基喹啉,产率从良好到优异,选择性也非常好。这种方法形成的硼化化合物可以通过已知的转化反应转化为各种重要的合成子。
