Abstract: A cobalt-catalyzed direct C-H carbonylative reaction of N-(2-(1H-indol-1-yl)phenyl)picolinamides for the synthesis of (NH)-indolo[1,2-a]quinoxalin-6(5H)-one skeletons has been developed. Using benzene-1,3,5-triyl triformate (TFBen) as the CO source and picolinamide as the traceless directing group, various free (NH)-indolo[1,2-a]quinoxalin-6(5H)-ones…
