Exo-1,2-diols 3 and 4 were efficiently converted into the corresponding allyl sulfides by means of tri-n-butylphosphine (Bu3P) and diphenyl disulfide (PhS)(2). This method was applied to the introduction of a carbon-carbon double bond from diol 11 to give allyl sulfide 12 in a highly regioselective manner. The allyl sulfide 12 was transformed into (-)-shikimic acid (1) in four steps. (C) 1998 Elsevier Science Ltd. All rights reserved.
