摘要

An efficient synthetic approach to variously substituted 2, 3-dihydrothiophenes has been developed. The reaction proceeded by copper-catalyzed tandem S-alkylation and S- alkenylation of sodium sulfide with 1, 4-diiodobut-1-enes to afford the corresponding 2, 3- dihydrothiophene derivatives in high yields. The 2, 3-dihydrothiophenes could bear alkyl, aryl as well as heteroaryl substituents. The resulted 2, 3-dihydrothiophenes could be ...
