The synthesis and structure determination of polypropionate is presented. An allyltitanium complex is first used in an allyltitanation reaction; titanium(IV) isopropoxide is next utilized as catalyst in an aldol–Tischtschenko reaction. This method promotes the formation of esters bearing five or six stereocenters in two steps with a very high level of diastereoselectivity and very high yield.
