参考标题:Synthesis Of C5-Allylindoles Through An Iridium-Catalyzed Asymmetric Allylic Substitution/oxidation Reaction Sequence Of N-Alkyl Indolines 作者:Jiamin Lu,Ruigang Xu,Haixia Zeng,Guofu Zhong,Meifang Wang,Zhigang Ni,Xiaofei Zeng |发布日期:2021.5.7 摘要:Iridium/brønsted Acid Cooperative Catalyzed Asymmetric Allylic Substitution Reactions At The C5 Position Of Indolines Have Been Reported For The First Time. The Highly Efficient Protocol Allows Rapid Access To Various C5-Allylated Products In Good To High Yields (48-97%) And Enantioselectivities (82% To >99% Ee) With Wide Functional Group Tolerance. The Transformations Allow Not Only The Formation
