A dual gold/silver-catalyzed cascade reaction was described for the synthesis of indolizines, yielding compounds with diverse functionalities in good to excellent yield. Furthermore, a gram-scale reaction was efficiently conducted in this study.
A dual gold/silver-catalyzed cascade C(sp(3))-H alkynylation/iminoauration of 2-substituted pyridines with hyper-valent 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(sp(3))-H functionalization, and a subsequent iminoauration process. A number of indolizines bearing diverse functionalities were prepared in good to excellent yield. Furthermore, a gram-scale reaction was efficiently conducted.
