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.
An efficient copper-catalyzed strategy for the synthesis of α-ketoamides via cross-coupling of methylketones and pyridin-2-amines is described. This transformation has provided a simple process fo...
We have developed a highly efficient method in the presence of copper catalyst to form amides from aminopyridines and aldehydes. This method is simple, environmental benign and has practical advantages in the amide synthesis. (C) 2013 Elsevier Ltd. All rights reserved.

Abstract A novel and efficient method for the synthesis of amide has been developed. The reactions proceeded smoothly under aqueous conditions at room temperature and generated the corresponding products in good to excellent yields. It is worth noting that alkyl amines which did not react in known approaches are well tolerated in our system.
