One-pot synthesis of 2,2′-bisbenzofurans using cuprous chloride as a catalyst
摘要:
A variety of novel 5,5'-disubstituted-2,2'-bisbenzofuran derivatives were synthesized by treatment of 4-substituted-2-(2-trimethylsilylethynyl)phenyl tert-butyldimethylsilyl ether analogues with Cud I as a catalyst in 62-82% isolated yields. This novel strategy provides a straightforward and simple pathway for the preparation of 2,2'-bisbenzofuran derivatives of interest in life and material sciences. (c) 2013 Elsevier Ltd.
