Nickel-Catalyzed Asymmetric Reductive Dicarbamoylation of Alkenes.
Jiaoyang WuChuan WangPublished in: Organic letters (2021)
Herein we report a nickel-catalyzed asymmetric reductive dicarbamoylation of alkenes, in which tethered carbamoyl chlorides and isocyanates serve as distinct electrophilic carbamoylating agents, providing new access to chiral oxindoles bearing an amide-substituted quaternary stereogenic center.
