Efficiency of chirality transfer in anionic oxy-Cope rearrangement depends solely on the orientational preference of the oxyanionic bond in the substrates with a single carbinol carbon chiral center. In chairlike transition-state conformations for the rearrangement of simplest substrates like anions generated from (E)-l-pheny1-1, 5-hexadien-3-01 and (E)-1, 5- heptadien-4-01, the oxyanionic bond is more prone to adopt the pseudoaxial orientation. ...
