Single enantiomers of (E)-1,5-diarylpentene-4,5-diols have been synthesised by Horner–Wittig elimination. The stereochemistry is controlled by an asymmetric dihydroxylation, and a stereoselective reduction of a β-keto phosphine oxide.

Dihydroxylation with solid OsCl3 to provide the catalytic oxidant, K3Fe(CN)(6) as stoichiometric oxidant, quinuclidine as the accelerating ligand with added K2CO3 and methanesulfonamide in a two-phase system (water and t-butanol) gives excellent yields of racemic syn diols from various alkenes (stilbenes, sulfides and phosphine oxides).
