A unique chemo- and regioselective α- and γ-arylation of palladium azapentadienyl intermediates is presented. Two distinct catalysts and sets of conditions successfully controlled the regioselectivity of the arylation. These methods provide the first umpolung C-H functionalization of azapentadienyl palladium intermediates and enable the divergent synthesis of allylic amine and enamine derivatives, which are of significant interest in the pharmaceutical industry.
本文报道了钯氮杂戊二烯中间体独特的化学选择性和区域选择性α-和γ-芳基化反应。两种不同的催化剂和条件成功地控制了芳基化反应的区域选择性。这些方法首次实现了氮杂戊二烯钯中间体的极性反转C-H官能团化，并能够发散性合成烯丙基胺和烯胺衍生物，这些衍生物在制药工业中具有重要意义。
