A gold‐catalyzed tandem cycloisomerization/ring expansion of alkynyl spiro‐epoxyoxindoles was developed, affording furo[2,3‐c]quinolinones in good to excellent yields with broad substrates scope. This methodology provides an efficient approach to construct furo[2,3‐c]quinolinone moieties. Moreover, the fluorescence properties of furo[2,3‐c]quinolinones are also investigated.
