Treatment of (allylthio)acetate with lithium diisopropylamide followed by the addition of s-butyllithium produced a new dianion which could react with a variety of alkylhalides exclusively at the allylic position. The high regioselectivity of the allylic alkylation could be realized in the case of methyl (allylthio)acetate dianion. A convenient and general method for the stereoselective synthesis
