Rearrangement of a series of 4-phenylsulfanyl-1,3-diols with TsOH gives tetrahydrofurans stereospecifically and in high yield even if the nucleophile is a secondary or tertiary alcohol. We discuss the stereochemistry and acceptable substution patterns of the diols which will carry out this reaction and define their limits. (C) 1996 Elsevier Science Ltd.
