Catalytic asymmetric oxidative carbonylation-induced kinetic resolution of sterically hindered benzylamines to chiral isoindolinones

Autor: Yi-Xue Nie, Xue-Wei Liu, Qiu-Qi Mu, Xing-Feng Bai, Hang Li, Zheng Xu, Li-Wen Xu

Publikováno v: Chemical Communications. 57:1778-1781

A highly enantioselective kinetic resolution of sterically hindered benzylamines has been achieved for the first time through transition-metal-catalyzed oxidative carbonylation, in which the new KR strategy offered a new approach to afford chiral iso

Silicon-mediated enantioselective synthesis of structurally diverse α-amino acid derivatives

Autor: Guan-Wu Yin, Li Li, Xing-Feng Bai, Jian Cao, Zheng Xu, Yu-Li Sun, Ke-Fang Yang, Li-Wen Xu, Yu-Ming Cui, Jun-Han Ma

Publikováno v: Science China Chemistry. 63:1082-1090

The catalytic asymmetric synthesis of novel and chiral amino acid derivatives with unconventional chemo-, diastereo-, and enantio-selectivity remains a paramount challenge. Herein we reported a novel protocol for the use of highly enantioselective co

Catalytic Asymmetric Carbonylation of Prochiral Sulfonamides via C–H Desymmetrization

Autor: Xing-Feng Bai, Li-Wen Xu, Zheng Xu, Qiu-Chao Mu, Ke-Fang Yang, Zhan-Jiang Zheng, Li Li, Chungu Xia

Publikováno v: ACS Catalysis. 9:1431-1436

An enantioselective oxidative C–H/N–H carbonylation process was developed in this work. A bimetallic Pd/Cu-based catalyst system was found to catalyze enantioselective C(sp2)–H carbonylation of prochiral arylsulfonamides via desymmetrization pr
