The use of inexpensive base metal catalysis to perform C–H activation is an active field of research in organic synthesis. Described herein is a sustainable cobalt-catalyzed diastereoselective oxidative annulation/double C–H activation of benzothiophene-[b]-1,1-dioxide with aminoquinolinamides under mild reaction conditions for the synthesis of annulated benzothiophenes.
