A γ-carbon activation method that operates through N-heterocyclic carbene/Brønsted acidcooperativecatalysis for highly enantioselective synthesis of δ-lactams is reported. The protocol allows the challenging remote γ-carbon control of regioselectivity and enantioselectivity through introduction of an appropriate γ-leaving group in the enals. The reaction offers good yields and excellent enantioselectivities

diisopropylamide, reacted with N-sulfonylaldimines 7 to produce the Mannich-type products N-[2,2-dichloro-3-(N-alkylimino)-1,3-diarylpropyl]benzenesulfonamides 11. The latter stable compounds were hydrolyzed at the imino functionality to afford N-[2,2-dichloro-3-oxo-1,3-diarylpropyl]benzenesulfonamides 12 in excellent yields. N-[2,2-Dichloro-3-(N-alkylimino)-1,3-diarylpropyl]benzenesulfonamides 11 were cyclized
