A nickel-catalyzed reductive coupling of alkynes and amides, followed by base-free transmetalation, proceeded selectively in the presence of an uncommon bidentate primary aminophosphine ligand to access highly functionalized indoles comprising biologically important trifluoromethyl groups and challenging electron-rich alkenyl groups at the 2-and 3-positions, respectively. Indole molecules were installed within natural products or drug molecules under mild conditions, and a trifluoromethylated analogue of a drug molecule (pravadoline) was also synthesized.
