A dual gold/silver-catalyzed cascade C(sp3)–H alkynylation/iminoauration of 2-substituted pyridines with hypervalent iodine(III) reagents for the synthesis of indolizines is described. This novel reaction involves the formation of an alkynyl Au(III) species, a dual gold/silver-catalyzed C(sp3)–H functionalization, and a subsequent iminoauration process. A number of indolizines bearing diverse functionalities
