Published: May 21, 2025

A nickel-catalyzed reductive 1,4-alkylacylation of 1,3-enynes has been established using nonactivated tertiary alkyl bromides and aromatic anhydrides as dual electrophiles. This protocol enables efficient assembly tetrasubstituted allenyl ketones with high chemo- regioselectivity. Mechanistic insights reveal the radical relay process involving synergistic interactions nickel zinc. The ketone products serve modular building blocks, particularly for constructing fully carbon-substituted furans via Au-catalyzed cycloisomerization selective 1,2-aryl migration, enhancing synthetic practicality.
