Cheap and clean! A novel Pd‐catalyzed oxidative intramolecular chloroamination of unactivated alkenes has been developed by using hydrogen peroxide as an oxidant and CaCl2 as a chlorine source. A series of chlorinated piperidine derivatives has been obtained with high regio‐ and diastereoselectivities at room temperature (see scheme).
便宜又干净!通过使用过氧化氢作为氧化剂和CaCl 2作为氯源,开发了一种新型的Pd催化的未活化烯烃的氧化分子内氯胺化反应。已获得一系列在室温下具有高区域选择性和非对映选择性的氯化哌啶衍生物(参见方案)。
