Mild Amide N-Arylation Enabled by Nickel-Photoredox Catalysis

This paper describes a mild strategy to promote amide arylations. Photoinduced oxidation of a Ni(II) aryl amido intermediate is proposed to facilitate the challenging C-N reductive elimination step at moderate temperatures. Notably, the mildly basic conditions employed facilitate access to a broad scope including protected amino acids, heterocycles, phenols, and sterically hindered substituents. Hence, this work presents an attractive strategy to enable late-stage functionalization of pre-existing amide moieties in commercial drugs and natural products.

Mild Sustainable Amide Alkylation Protocol Enables a Broad Orthogonal Scope

Herein, the development of a mild sustainable protocol to couple primary alkyl chlorides and bromides with amides is described. In contrast to current methodologies, our system does not require the use of strongly basic conditions, high temperatures, or the addition of an organometallic catalyst, thereby enabling access to a remarkably orthogonal scope. K₃PO₄ is used to facilitate the formation of secondary and tertiary amides, which are ubiquitous scaffolds in bioactive molecules and natural products. Alkylated amide products are obtained in good to excellent yields, with no substantial limitations observed based on the steric and electronic properties of either coupling partner.
