Catalyst-controlled directing group translocation in the site selective C-H functionalization of 3-carboxamide indoles and metallocarbenes.

ABSTRACT: Complementary methods toward the selective functionalization of indole and oxindole frameworks employing an alternative strategy in heteroaryl C-H functionalizations are presented herein. This work focuses on a catalyst-controlled, site selective C-H activation/functionalization of 3-acyl indoles, wherein an amide serves as a robust and versatile directing group capable of undergoing concomitant 1,2-acyl translocation/C-H functionalization in the presence of a Rh^I/Ag^I co-catalysts to provide the cross-coupled adducts in high yields. In contrast, the use of Ir^III/Ag^I catalysts subverted the 1,2-acyl migration to afford the corresponding C2-functionalized products in good to excellent yields. A notable feature of the catalyst systems was the except
