Recent studies have demonstrated that amides can be used in nickel-catalyzed reactions that lead to cleavage of the amide C–N bond, with formation of a C–C or C–heteroatom bond. However, the general scope of these methodologies has been restricted to amides where the carbonyl is directly attached to an arene or heteroarene. We now report the nickel-catalyzed esterification of amides derived from aliphatic carboxylic acids. The transformation requires only a slight excess of the alcohol nucleophile and is tolerant of heterocycles, substrates with epimerizable stereocenters, and sterically congested coupling partners. Moreover, a series of amide competition experiments establish selectivity principles that will aid future synthetic design. These studies overcome a critical limitation of current Ni-catalyzed amide couplings and are expected to further stimulate the use of amides as synthetic building blocks in C–N bond cleavage processes. Recent studies on nickel-catalyzed activation of amides have been shown to forge C–C or –heteroatom bonds through cleavage on the amide C–N bond. We report the first nickel-catalyzed activation of amides derived from aliphatic carboxylic acids, thus overcoming the key limitation associated with nickel-catalyzed couplings of amides.
