Abstract

Gold-Catalyzed Redox Synthesis of Imidazo[1,2-a]pyridines Using Pyridine N-Oxide and Alkynes. -The reaction is sensitive to the steric effects and does not tolerate tBu-or mesityl-substituents. Disubstituted alkynes do not produce any desired product. The reaction conditions are applicable to chiral alkynes. -(TALBOT, E. P. A.; RICHARDSON, M.; MCKENNA, J. M.; TOSTE*, F. D.; Adv. Synth.
