Palladium-catalyzed cascade cyclization of α,β-unsaturated N-tosylhydrazones with iodoarenes : access to 2H-chromenes and 2H-quinolines

A palladium-catalyzed cascade reaction of α,β-unsaturated N-tosylhydrazones with iodoarene derivatives containing a nucleophilic group has been developed, which provides a facile approach to 2H-chromenes and 2H-quinolines, respectively. Additionally, the double...
