Carbocatalytic Cascade Synthesis of Polysubstituted Quinolines from Aldehydes and 2‐Vinyl Anilines

Oxidized active carbon (oAC) catalyses the formation of polysubstituted quinolines from o-vinyl anilines and aldehydes. The reaction proceeds in a cascade manner through condensation, electrocyclization dehydrogenation, gives access to wide range with alkyl and/or aryl substituents as demonstrated 40 examples. metal-free catalytic procedure allows heterogeneous protocol for synthesis various quinolines. mechanistic studies imply that both acid quinoidic groups oAC are integral manifold.
