A series of 4-arylsulfonylimino-4,5-dihydrofurans (14 examples) were efficiently synthesized in good to excellent yields by using the copper-catalyzed three-component reaction between sulfonyl azides, phenylacetylene, and β-ketoesters in tetrahydrofuran (THF) at 40 °C for 8 h in the presence of triethylamine (TEA). A plausible mechanism for this process is proposed.
