A tandem Wittig Rearrangement/aldol reaction of O-benzyl or O-allyl glycolate esters generates two carbon-carbon bonds and two contiguous stereocenters with excellent diastereoselectivity in a single step from simple starting materials. The [1,2]-Wittig rearrangement proceeds under very mild reaction conditions.
