N-(pyridine-2-yl)amides in water from ketones and 2-aminopyridine via direct oxidative C–C bond cleavage has been developed. A series of ketones, including more challenging inactive aromaticketones substituted with diverse long-chain alkyl groups, were selectively converted to N-(pyridine-2-yl)amides. Furthermore, the protocol can be applied to aryl alkyl carbinols to afford the corresponding amides in moderate

Herein, we 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

The present invention is directed to bicyclic heteroaryl benzamide compounds of formulas (I) which are tropomyosin-related kinase (Trk) family protein kinase inhibitors, and hence are useful in the treatment of pain, inflammation, cancer, restenosis, atherosclerosis, psoriasis, thrombosis, a disease, disorder, injury, or malfunction relating to dysmyelination or demyelination or a disease or disorder associated with abnormal activities of nerve growth factor (NGF) receptor TrkA.
A procedure for the synthesis of N-heteroaryl amides directly from oxidative amidation of aldehydes catalyzed by heteropolyanion-based ionic liquids has been reported. The proposed N-directing dual-catalysis mechanism was briefly investigated.

cleavage of C(CO)–C(alkyl) bond to generate N-substitutedbenzamides has been developed in the presence of copper(I) chloride. The usage of inexpensive copper catalyst, broad substrate scope, mild conditions make this protocol very practical. More importantly, this reaction provides an alternative approach for the construction of useful N-substitutedbenzamides.
