The [2,3] Wittig rearrangements of the lithio enolates of the cisconfigurated allylic ethers 5a -d are stereoselective. The tert-butyl ester 5d gives 79% of a single rearrangement product 6d. The chiral center of the dioxolane controls the configuration at one of the newly formed stereogenic centers
