Nickel‐Catalyzed Asymmetric Synthesis of α‐Arylbenzamides


Cuesta‐Galisteo, Sergio; Schörgenhumer, Johannes; Wei, Xiaofeng; Merino, Estíbaliz; Nevado, Cristina (2021). Nickel‐Catalyzed Asymmetric Synthesis of α‐Arylbenzamides. Angewandte Chemie Internationale Edition, 60(3):1605-1609.

Abstract

A nickel‐catalyzed asymmetric reductive hydroarylation of vinyl amides to produce enantioenriched α‐arylbenzamides is reported. The use of a chiral bisimidazoline (BIm) ligand, in combination with diethoxymethylsilane and aryl halides, enables the regioselective introduction of aryl groups to the internal position of the olefin, forging a new stereogenic center α to the N atom. The use of neutral reagents and mild reaction conditions provides simple access to pharmacologically relevant motifs present in anticancer, SARS‐CoV PLpro inhibitors, and KCNQ channel openers.
