    摘要: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.
