Developing new organic reactions with excellent atom economy and high selectivity is significant urgent. Herein, by ingeniously regulating the reaction conditions, highly selective transformations of propargylamines have been successfully implemented. The palladium-catalyzed cyclization generates a series functionalized quinoline heterocycles, while base-promoted isomerization affords diverse 1-azadienes. Both good functional group tolerance, mild yields up to 93%. More importantly, these heterocycles 1-azadienes could be flexibly transformed into valuable compounds, illustrating validity practicability propargylamine-based reactions.

Abstract Due to the generation of multiple intermediates during nitroarene reduction, precise interception single one develop tandem reactions involving both C−C and C−N bond formations still remains a significant challenge. Herein, relay catalysis supported bifunctional cobalt catalyst with l ‐proline has been successfully applied establish bran‐new reductive annulation reaction nitroarenes formaldehyde, which enables direct diverse construction symmetrical unsymmetrical 1,3‐diaryl imidazolines. It proceeds operational simplicity, good substrate functionality compatibility, excellent step atom‐efficiency. Mechanistic studies reveal that Co‐catalyst exhibits synergistic effect on formation key N ‐hydroxy imine, subsequently facilitates formation. The current work opens door useful transformations by reduction‐interrupted strategy.
