tetrahydropyrroloindoles and hexahydropyrroloquinolines of general structure 8 is described. These products are formed through cascade Pd-catalyzed coupling reactions between aryl chlorides and unsaturated amine substrates 5. A single catalyst effects an intramolecular N-arylation reaction followed by an intermolecular alkene carboamination reaction to generate two rings, three bonds, and one stereocenter with
描述了一种立体选择性合成通式8的四氢吡咯并吲哚和六氢吡咯并喹啉的新方法。这些产品是通过芳基氯和不饱和胺底物5之间的级联 Pd 催化偶联反应形成的。单一催化剂进行分子内 N-芳基化反应,然后进行分子间烯烃碳胺化反应,生成两个环、三个键和一个立体中心,具有良好的化学选择性、非对映选择性和化学产率。
