Chen, Hong-Bin published the artcileAccessing 2-Arylbenzofurans by CuI2(pip)2-Catalyzed Tandem Coupling/Cyclization Reaction: Mechanistic Studies and Application to the Synthesis of Stemofuran A and Moracin M, Product Details of C14H10O4, the publication is Asian Journal of Organic Chemistry (2016), 5(11), 1345-1352, database is CAplus.
An asym. dinuclear copper(I) complex, CuI2(pip)2 (pip = (2-picolyliminomethyl)pyrrole anion), was utilized to catalyze the tandem coupling/cyclization reaction of o-iodophenols and terminal alkynes, which led to the formation of valuable 2-arylbenzofurans I (R1 = Ph, 4-EtC6H4, 1-naphthyl, etc.; R2 = H, 4-MeO, 4-t-Bu, 4-Ph, 4-F, 4-Br) in good yields. DFT calculations showed that the two proximate copper atoms play cooperative roles throughout the catalytic cycle. Using this catalytic protocol, bioactive natural products stemofuran A and moracin M were concisely synthesized.
