Macrocyclic ketene acetals 3 undergo Claisenrearrangements smoothly and constitute a viable and general approach to hetero- or carbocyclic ring systems 4. This novel ring contraction process is subject to high internal asymmetric induction (cf. lactones 7 → carbocycles 8) as well as relative asymmetric induction in the rearrangements of ketene acetals derived from lactones 18, 23 and 27. Finally,
