Copper-catalyzed multicomponent reaction: synthesis of 4-arylsulfonylimino-4,5-dihydrofuran derivatives

J Org Chem. 2010 Aug 20;75(16):5743-5. doi: 10.1021/jo1010075.

Abstract

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 beta-ketoesters in tetrahydrofuran (THF) at 40 degrees C for 8 h in the presence of triethylamine (TEA). A plausible mechanism for this process is proposed.
