title: Transition-Metal-Free Tandem Chlorocyclization of Amines with Carboxylic Acids: Access to Chloroimidazo[1,2-α]pyridines.
abstract: An efficient one-pot and transition-metal-free chlorocyclization cascade of 2-aminopyridines with aliphatic carboxylic acids is reported. This transformation provides a novel approach to 2-chloro- or 3-chloro-substituted imidazo[1, 2-α]pyridines with a broad range of substrate scopes.
