Herein, a novel cobalt(III)‐catalyzed and TFA‐controlled [3+2+1] cyclization of diverse anilines and terminal alkynes has been realized by using DMSO as both the solvent and the C1 source, which led to the specific synthesis of privileged 3‐arylquinolines in one pot and regioselectively. Mechanistic investigations revealed that this versatile transformation might be initiated with a C−H activation

The synthesis of 3-arylquinolines through a cyclocondensation of 2-aminoarylmethanols and benzaldehydes in DMSO promoted by KOBu has been developed. In this procedure, DMSO is used not only as a solvent, but also a C1 source incorporated into the 2-position of quinoline ring.
