Carbazole derivatives are prominent structural motifs of many bioactive natural products, pharmaceuticals and materials,[1, 2] and intense efforts have focused on the development of effective methods to synthesize these compounds.[3] Recently, intramolecular amination strategies [3g, 4–7] have been reported, as shown in Scheme 1. These have included transition-metal-catalyzed CÀN formation with halide-functionalized arenes;[4] metal- ...
