Palladium-catalyzed synthesis of benzofurans via C–H activation/oxidation tandem reaction and its application to the synthesis of decursivine and serotobenine
A new palladium-catalyzed method for the synthesis of benzofurans by reaction of 2-hydroxystyrenes and iodobenzenes via a CâH activation/oxidation tandem reaction has been unprecedentedly discovered. By using this strategy, the overall synthetic efficiency of the synthesis of decursivine and its analogues was indeed improved. Preliminary mechanistic studies shed light into the possible mechanisms.
An approach to synthesize 2,3-diaryl benzo[b]furans using coumarins and aryl bromides is developed.

A natural product inspired library was synthesized based on 2,3-diarylbenzofuran and 2,3-diaryl-2,3-dihydrobenzofuran scaffolds. The library of forty-eight compounds was prepared by utilizing Pd-catalyzed one-pot multicomponent reactions and ruthenium-catalyzed intramolecular carbenoid C-H insertions. The compounds were evaluated for antibacterial activity in a panel of test systems including phenotypic
(p-MeOC6H4)2(p-MeOC6H4CO)C+SbF6– has been prepared as a stable crystalline salt from the corresponding chloride and silver hexafluoroantimonate; when heated in 1,2-dichloroethane this cation affords 2,3-bis-(p-methoxyphenyl)-6-methoxybenzofuran (5)via cyclization.
Friedel-Crafts alkylation oxidative cyclization catalyzed by co-oxidation of SeO<sub>2</sub> and FeCl<sub>3</sub>: a simple synthesis of benzo[<i>b</i>]furan from acetophenone and anisole
Abstract A simple one-pot method was developed to complete the α-diphenyl substitution and cyclization of acetophenone using acetophenone and substituted benzene as substrates, and a series of benzofuran derivatives was synthesized efficiently. It had the advantages of medium to excellent yield and easily obtained substrate. Compared with other methods, the method avoids the use of precious metals
