专利号:US-7473786-B1 优先权日:2003-12-05 标题:Methods and systems for preparing fused heterocyclic compounds using copper(I) catalysts 发明人:VENKATARAMAN DHANDAPANI; BATES CRAIG G; SAEJUENG PRANORM 权利人:UNIV MASSACHUSETTS 摘要:A copper(I)-catalyzed procedure for the synthesis of benzo[b]heterocycles. This protocol can be used to synthesize a variety of 2-arylbenzo[b]furans and indoles in good to excellent yields. This method can tolerate a variety of functional groups, does not require the use of expensive additives and is palladium-free.
