An intramolecular palladium(0)-mediated α-arylation of ketones applied to the synthesis of various substituted tetracyclic indoles is reported. Most significantly, the efficiency of the transformation was enhanced by the use of monoligated Pd(0) complexes. This methodology was extended to double α-arylation of ketones using one-pot reactions with either simultaneous addition or sequential addition
报道了分子内钯(0)介导的酮的α-芳基化反应,用于合成各种取代的四环吲哚。最重要的是,通过使用单连接的Pd(0)配合物可以提高转化效率。使用一锅反应,同时添加或顺序添加两个芳基卤化物以生产芳基取代的四环吲哚,将该方法扩展为使用双锅反应使酮进行双α-芳基化。
