one‐pot ligand‐free palladium‐catalyzed α,β‐dehydrogenation of ketone and sequential aza‐Micahel addition was developed, which provides N‐Tf 2‐aryl‐2,3‐dihydroquinolin‐4(1H)‐ones in moderate to good yields. This catalytic reaction provides simple and mild reaction conditions, a wide scope of substrates to biologically interesting N‐heterocycles.
