Silver-catalyzed direct couplings of 2-substituted furans with cyclic 1,3-dicarbonyls

Direct alkenylation of 2-substituted furans with cyclic 1,3-dicarbonyls by means of silver catalysis have been explored. Silver salts resulted more efficient than a variety of Lewis acids and p-TsOH.

Silver salts are more efficient than a variety of Lewis acids and p-TsOH in promoting direct alkenylation of 2-substituted furans by their reaction with 1,3-dicarbonyls.Figure optionsDownload as PowerPoint slide
