A variety of 3-functionalized benzo[b]furans were achieved by way of a FeCl3-medlated Intramolecular cyclization of electron-rich a-aryl ketones. The alkoxy substituent on the benzene ring In the substrates was essential for an efficient cyclization to occur. This novel method allows the construction of benzo[b]furan rings by joining the O-atom on the side chain to the benzene ring via direct oxidative aromatic C-O bond formation.
