Abstract
New chiral rhenium complexes of allylic, homoallylic and propargylic a lcohols have been prepared and their reactivity versus various reagent s has been studied. Starting from the allyl alcohol complex, a multist ep sequence involving a chemoselective oxidation, a Wittig reaction an d a reduction led without bond-shift to conjugated dienone and dienol. The complexed allyl acetate, prepared by reaction of acetic anhydride on the complexed allyl alcohol reacted with sodium dimethylmalonate i n a diastereoselective fashion.
