Remote stereocontrol in the Ireland–Claisen rearrangement using a chiral acetonide that serves as internal stereocontrol element is an effective and general method for chirality transfer from a δ-hydroxyl group in the allylic alcohol unit. This strategy circumvents the need for redundant chirality at the α-position allylic alcohol, while simultaneously producing a terminal alkene that can streamline
