Abstract: A novel gold(I)/Brønsted acid relay catalysis enabling azofuran activation to induce annulative rearrangement from 3-yne-1,2-diols and aryldiazonium tetrafluoroborates is reported, producing a series of furan-2-yl-substituted pyrrol-2-ones bearing a quaternary carbon center with good yields.
