Alandini, Nurtalya published the artcileAmide Synthesis by Nickel/Photoredox-Catalyzed Direct Carbamoylation of (Hetero)Aryl Bromides, Recommanded Product: 4-Methoxy-N-phenylbenzamide, the main research area is amide preparation nickel photoredox catalyst carbamoylation heteroaryl bromide; amides; cross-coupling; nickel catalysis; photoredox catalysis; radical chemistry.

Herein, the authors report a one-electron strategy for catalytic amide synthesis that enables the direct carbamoylation of (hetero)aryl bromides. This radical cross-coupling approach, which is based on the combination of nickel and photoredox catalysis, proceeds at ambient temperature and uses readily available dihydropyridines as precursors of carbamoyl radicals. The method’s mild reaction conditions make it tolerant of sensitive-functional-group-containing substrates and allow the installation of an amide scaffold within biol. relevant heterocycles. In addition, the authors installed amide functionalities bearing electron-poor and sterically hindered amine moieties, which would be difficult to prepare with classical dehydrative condensation methods.

Rahman, Mahbubur Md. published the artcileMetal-Free Transamidation of Secondary Amides by N-C Cleavage, Application of 4-Methoxy-N-phenylbenzamide, the main research area is secondary amide transamidation nitrogen carbon bond cleavage.

Transamidation reactions represent a fundamental chem. process involving conversion of one amide functional group into another. Herein, the authors report a facile, highly chemoselective method for transamidation of N-tert-butoxycarbonylation (N-Boc) activated secondary amides that proceeds under exceedingly mild conditions in the absence of any additives. Because this reaction was performed in the absence of metals, oxidants, or reductants, the reaction tolerates a large number of useful functionalities. The reaction is compatible with diverse amides and nucleophilic amines, affording the transamidation products in excellent yields through direct nucleophilic addition to the amide bond. The utility of this methodol. is highlighted in the synthesis of Tigan, a com. antiemetic, directly from the amide bond. The authors expect that this new metal-free transamidation will have broad implications for the development of new transformations involving direct nucleophilic addition to the amide bond as a key step.
