The combination of triazole-gold (TA-Au) and copper catalysts enabled a synthesis of substituted furans in an one-pot three-step reaction cascade. The reaction tolerates a large substrate scope with simple starting materials and provides di-, tri-, and tetrasubstituted furans in good to excellent yields.
