2-aminopyridines with alkynoic acids has been developed for the synthesis of 2-haloimidazo[1,2-a]pyridines. In this reaction, two C-N bonds and one C-halogen bond are formed in one pot, generating the desired products in good yields. This is the first report for the synthesis of 2- haloimidazo [1,2-a]pyridine derivatives from alkynoic acids.

Transition-Metal-Free Tandem Chlorocyclization of Amines with Carboxylic Acids: Access to Chloroimidazo[1,2-α]pyridines
An efficient one-pot and transition-metal-free chlorocyclization cascade of 2-aminopyridines with aliphatic carboxylicacids 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.
