strategy is based on an unprecedented diastereoselective, intramolecular phenol para-alkylation to a cross-conjugatedcyclohexadienone. In the course of these synthetic studies we developed rapid access to a chiral nitrile possessing a quaternary stereocenter and disclose an unusual acetal rearrangement from a dioxane, which favors the corresponding dioxepane.
