A convenient and general method for the synthesis of stereochemicallydefined dienes from allylic phosphonium salts under simple conditions is described. Selective preparation of trisubstituted dienes was performed with good-to-excellent yields in mild basic aqueous medium. Preparation of 3-deuterated products was also readily achieved when H2O was replaced with D2O as the solvent.
