Toward versatile methods leading to highly functionalized imidazo[1,2-a]pyridines
摘要:
A convenient and general method of preparation of polyfunctionalized imidazo[1,2-a]pyridines is reported. This methodology involves activation of secondary amides leading to the formation of the corresponding amidines 9. Different activating reagents have been evaluated and the efficiency of PCl5 was illustrated with alkyl functionalized groups. (C) 2012 Elsevier Ltd. All rights reserved.
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.
