Three become one: Multiply substituted quinolines were synthesized from diaryliodoniums, alkynes, and nitriles by a CuII‐catalyzed method. This cascade annulation is highly regioselective, step‐economic, flexible with regard to the functional groups, and could potentially be applied to the synthesis of complex molecules.

A copper-catalyzed tandem arylation–cyclization process to access 1-(arylthio)isoquinolines from isothiocyanates and diaryliodonium salts is described. It is the first general method to construct the potentially useful 1-(arylthio)isoquinoline derivatives. Moreover, 1-(methylthio)isoquinoline derivatives were also achieved successfully with MeOTf instead of diaryliodonium salts under metal-free conditions
