Enantioselective Reductive Conjugate Alkenylation of α,β-Unsaturated Ketones and Amides via Nickel Catalysis
Mengxin Zhao, Luoqiang Zhang, Jianrong Steve Zhou
Abstract
Chiral nickel complexes promoted enantioselective reductive alkenylation of a range of conjugated enones, using alkenyl bromides, triflates, and tosylates. The neutral condition was compatible with sensitive groups and azaheteroaryl rings. Importantly, alkenyl groups in products can be readily converted to functionalized alkyl groups via iron-catalyzed reductive hydrofunctionalization. Some examples of asymmetric alkenylation of N -enoyl pyrroles and indoles were also included.
