The dienolates derived from the chiral imides (I) and (IV) undergo asymmetric α-oxylation with dibenzyl peroxydicarbonate to give the (E)-or (Z)-products (III) and (V) highly selectively. Both undergo thermal rearrangements to provide the γ-(S)-or γ-(R)-oxy-substituted derivatives with efficient asy
