Stereoselective transformation of easily available (2Z,4E)-2,4-alkadien-1-ols into (E)-3-alkene-1,2,5-triol derivatives

Synthesis of 3-alkenyl-1,2,5-triol derivatives, potentially useful intermediates in organic synthesis, is established, which constitutes stereoselective epoxidation of the hitherto hardly accessible dienyl alcohols of the cis,trans stereochemistry followed by Pd-catalyzed reaction with AcOH.
