Gold Catalysed Redox Synthesis of Imidazo[1,2- a]pyridine using Pyridine N-Oxide and Alkynes
{{output}}
A mild, catalytic, atom economical synthesis of imidazo[1,2-a]pyridines has been developed: catalytic PicAuCl2 in the presence of an acid produces a range imidazo[1,2-a]pyridines in good yield. This strategy is mild and forseen to be of particular use for the ... ...
