Polysubstituted 5‐ and 6‐membered carbocycles were synthesized by the title reaction. The one‐pot dynamic relay process generates four new stereocenters, including a quaternary carbon center, in a highly enantioselective fashion (99.5:0.5→99:0.5 e.r.) by using a simple combination of palladium and chiral amine co‐catalysts.
通过标题反应合成了多取代的5元和6元碳环。单锅动态中继过程通过使用钯和手性胺助催化剂的简单组合,以高度对映选择性的方式(99.5:0.5→99:0.5 er)生成了四个新的立体中心,包括一个季碳中心。
