A facile and mild protocol for the synthesis of substituted tetrahydrofurans, 2-deoxy C-aryl glycoside and C-aryl glycosides is described by use of 20 mol%, FeCl3, or Yb(OTf)(3) as acid catalysts. The benzylic carbocation generated undergoes intramolecular substitution by the oxygen nucleophile to result the tetrahydrofurans and C-aryl glycosides. (C) 2002 Elsevier Science Ltd.
